This invention is generally related to the fields of fragrance compositions, personal care products, and home consumer products. This invention also relates to 20-pregnenes, in particular those found naturally occurring in corals and which affect mood in humans, to the incorporation of these 20-pregnene compounds into various compositions, and to methods of affecting the mood of individuals using such compounds.
Marine pregnenes are substances from the pregnene family which have at least one double bond, and which occur naturally in organisms that dwell in the sea. Pregna-5,20-dien-3β-ol, also known as muricin aglycone, has been described as a constituent of the Alyconacean coral Gersemia rubiformis, commonly referred to as sea raspberry, inhabiting the cold waters off the coast of Newfoundland and Labrador (Kingston et al., J.C.S. Perkin I, 1979, 2064). Muricin aglycone also occurs in the coral Carijoa riisei (Telestacea) off the coast of the Brazilian island of Guaibinha (Maia et al., Bol. Soc. Chil. Quim., 1998, 43(1), 39). Muricin aglycone also occurs in the South African soft coral, Pieterfaurea unilobata (Beukes et al., J. Nat. Prod., 1997, 60, 573). In addition, muricin itself, wherein the steroid moiety is conjugated with a sugar, occurs in the gorgonian coral, Muricea fruticosa, off the coast of California (Bandurraga and Fenical, Tetrahedron, 1985, 41(6), 1057). Pregna-1,4,20-trien-3-one, pregna-1,20-dien-3-one, and pregn-20-en-3α-yl acetate have been found to occur in an unidentified soft coral off the coast of Canton Island (Higgs and Faulkner, Steroids, 1977, 30(3), 379). Pregna-1,4,20-trien-3-one also occurs in the Alyconacean coral Gersemia rubiformis (Kingston et al., J.C.S. Perkin I, 1979, 2064), and is the major steroidal component of the coral Carijoa riisei (Telestacea) (Maia et al., Bol. Soc. Chil. Quim., 1998, 43(1), 39).
Materials derived from marine organisms, such as ambergris, have been used in perfumery as odorants and/or fixatives. However, they are not known to produce a particular psychological effect. Muricin aglycone has been subject to testing for biological activity. For example, muricin aglycone was evaluated as an inhibitor of human testicular 17α Hydroxylase/C17,20-Lyase (Li et al., J. Med. Chem. 1996, 39, 4335; Brodie et al. U.S. Pat. No. 5,994,334, 1999). Compounds with a hydrophobic D-ring, including muricin aglycone, showed little activity in this assay. Likewise, muricin aglycone has been tested for inhibition of rabbit and rat cytochrome P-450 (Halperper sect et al., Mol. Pharmacol., 1989, 35(1), 148; Klekotka et al., J. Pharmacol. Exp. Ther., 1995, 274(3), 1450). Muricin aglycone has been found to elicit cross adaptation with androsta-4,16-dien-3-one in the local electrical response of the human vomeronasal epithelium (Monti-Bloch et al., Psychoneuroendocrinology 1994, 19, 673). Androsta-4,16-dien-3-one has been found to produce a reduction of negative affect when administered nasally to humans (Grosser et al., Psychoneuroendocrinology, 2000, 25, 289).
As has been the case for ambergris from the sperm whale, the harvesting of the naturally occurring 20-pregnenes from coral is neither efficient, nor cost effective, nor ecologically sound. Consequently, as is the case for ambergris, a synthetic approach is desirable. The synthesis of several of these 20-pregnenes has been described in the literature. Pregnenolone hydrazone was treated with iodine and triethylamine to give the vinyl iodide, which was then treated with sodium and ethanol to give pregna-5,20-dien-3β-ol (Krubiner et al., J. Org. Chem., 1969, 34, 11, 3502). Pregna-5,20-dien-3β-ol has also been synthesized from pregnenolone acetate by conversion to the corresponding alcohol, from which the mesylate was prepared followed by treatment with potassium t-butoxide (Dawe and Wright, Can. J. Chem., 1987, 65, 666). The first described synthesis of pregna-5,20-dien-3β-ol started with 3-acetoxybisnorcholenic acid. This was subjected to Curtius rearrangement, N-methylation, and Hofmann degradation (Julian et al., J. Amer. Chem. Soc., 1948, 70, 887). Pregna-5,20-dien-3β-ol was synthesized from pregnenolone by converting to the ethylene thioketal, and then treating with Raney nickel (Kingston et al., J.C.S. Perkin I, 1979, 2064). These same authors used similar methodology for synthesizing pregna-1,4,20-trien-3-one, also in the Sea Raspberry, from progesterone. Pregna-5,20-dien-3β-ol may also be synthesized by the treatment of pregnenolone tosylhydrazone with methyl lithium (Bose and Steinberg, Synthesis, 1970, 595). 5α-pregna-1,20-dien-3-one, as well as 5α-pregn-20-en-3β-ol, have also been synthesized via the same tosylhydrazone method (Schow and McMorris, Steroids, 1977, 30, 389).

After stirring for one hour at −78° C., 0.21 g (0.0011 mole) of benzeneselenyl chloride in 1.5 ml of dry tetrahydrofuran was added quickly to the enolate solution. The reaction mixture is stirred for thirty minutes, then water (10 ml) was added and the mixture extracted with ether (4×20 ml). The combined extracts are washed with dilute hydrochloric acid (10%, 2×10 ml), saturated sodium bicarbonate solution (15 ml), water, dried, and the solvent removed. The crude product is dissolved in ethyl acetate (2 ml) and methanol (2 ml), and 0.5 g (0.0023 mole) of sodium metaperiodate dissolved in enough water-methanol-ethyl acetate to maintain solution is added. The reaction mixture is stirred for one hour, then water (20 ml) added and the mixture extracted with ether (4×15 ml). The combined extracts are dried and the solvent removed, leaving the product, which is purified by chromatography on silica gel (200 mesh with hexane-ethyl acetate, 100:5). This gives 0.082 g (2.8×10−4 mole, 55%) of the dienone (11), which on recrystallization from hexane-dichloromethane had mp 124-126° C. λmax (CH3OH) 228 nm (1.04×104); λmax 1692, 1648 cm−1; δ 0.63 (s, C-18 Me), 1.02 (s, C-19 Me), 4.94-5.01 (m, C-21H), 5.78 (m, C-20H), 5.85 (d, J=10.2 Hz, C-2H), 7.16 (d, J=10.2 Hz, C-1H); MS, m/e 298.230 (68% M+; calcd. for C21H30O: 298.2298), 283 (M-15), 270 (M-CH2CH2), 122 (100% C8H10O); CD (θ) 337-470 (CH3OH).

The effect of pregna-5,20-dien-3β-ol in comparison to ADO on nasal chemosensory receptors were determined as described in L. Monti-Bloch et al., (1994) Psychoneuroendocrinology 19(5-7):673-686.
Similar quantities of androstadienone (ADO-1) (27 picograms) and muricin aglycone (pregna-5,20-dien-3β-ol) (1) (30 picograms) induced robust depolarization of the electrogram of peripheral nasal chemosensory receptors. Repeated stimulation with muricin aglycone (1, 2, 3) produces fatigue of the receptors as shown by the electrogram induced by subsequently delivered androstadienone (ADO-2), as shown in
The physiologic and psychological effects of pregna-5,20-dien-3β-ol were investigated in men and women. Additionally, the local and general tolerability and safety of pregna-5,20-dien-3β-ol delivered airborne to the nasal passages were also evaluated.
We assessed the resulting physiological responses and behavioral changes induced by nasal exposure to 12 ng pregna-5,20-dien-3β-ol in 76 volunteers (38 women and 38 men), age 18 to 46 (Table 1) using a placebo-controlled, single blind and crossover study design. The study design is schematically summarized in
Healthy volunteers, recruited through advertisement in bulletin boards at the University of Utah campus, participated upon signed consent in a single study session lasting 2 hours and 10 minutes. Exclusion criteria for participation were pregnancy, use of psychotropic medication, substance abuse, alcohol abuse, steroidal contraceptives and any neuropsychiatric condition ascertained by interview. At the beginning of the session each volunteer answered a questionnaire about his or her health. Women participants were also requested to complete a brief menstrual calendar.

Subjects who participated were asked, as a baseline, to fill out the modified DABS-70 as to their personality characteristics and feelings as they currently perceived them. Each item was quantified ranging from an individual's perception of “not at all” (0) to “extremely” (4). At the beginning of the questionnaire was a statement that they might feel differently after the blind and randomized exposure to the contents of a perfumery grade smelling strip positioned on the upper lip. The baseline electrophysiological measurements were performed after the questionnaire was completed, and again 5 minutes before the second randomized exposure (
Upon completion of the first DABS-70, each subject was invited to rest supine in a comfortable medical bed in a quiet room and several non-invasive electrode leads and transducers were positioned on the surface skin of the arms, face and skull to help measure physiologic parameters (

During the course of a recording session, physiologic readings were performed in four consecutive instances, before and after randomized administration of active substance or control (
All physiological recordings were pre-amplified and digitized (Biopac Systems), and continuously computer monitored and stored (Macintosh G3), for further off-line processing and analysis (for a detailed explanation see Monti-Bloch et al, 1994, 1998).
Administration of pregna-5,20-dien-β-ol and Control (Placebo)
Active substance (pregna-5,20-dien-3β-ol) and control were freshly prepared on 0.7 cm×10 cm perfumery grade smelling strips 24 hours before the experiment. A perfumery grade smelling strip was positioned on the upper lip of the subject for delivery of control or active substance to the nasal passages for a period of 20 minutes. Each breath carried vapors of pregna-5,20-dien-3β-ol or control (air) from the paper strip to the nasal passages.
Perfumery grade smelling strips containing either pregna-5,20-dien-3β-ol or control were prepared as follows: 100 μl of stock solution containing 100 mg pregna-5,20-dien-3β-ol/10 mL ethanol (95%) was added to a clean paper strip. Ethanol was allowed to evaporate overnight in a clean fume hood, and 1 mg of dry crystals of pregna-5,20-dien-3β-ol remained embedded in the dried perfumery grade smelling strip. Control was a perfumery grade smelling strip prepared following the same procedure but the solution was devoid of active substance.
The following assumptions were used to calculate the quantity of pregna-5,20-dien-3β-ol delivered to the nasal passages during a study session: a) the quantity of pregna-5,20-dien-3β-ol arriving to the nasal passages with each breath is ≈40 pg (determined as described below); b) the average respiratory rate at rest in men and women is ≈15 breaths per minute; and c) the subject was exposed to pregna-5,20-dien-3β-ol for 20 min during the entire study session. The total calculated quantity of pregna-5,20-dien-3β-ol delivered to the nasal passages over 20 min (exposure during the study session) was calculated as follows: 40 pg/breath×15 breaths/min×20 min=12000 pg=12 ng.
The very small amount of an active substance delivered in vapor form to the nasal passages was calculated using the data described in the following experiment:
10 mg of active substance in crystal form (powder) was embedded in a sterile cotton pellet. The cotton pellet was positioned in a sterile glass chamber connected to a source of pulsatile clean (sterile) air. The pulsatile air flow was 1 ml per second. The output of the glass chamber (air saturated with active substance, or vapor pulses) was collected (bubbled) during 48 hours in a test tube containing ethanol. At the end of the 48 hour period ethanol was allowed to evaporate, and the quantity of active substance collected during the 48-hour period was measured. The procedure was performed at room temperature.
Quantity of substance collected during 48 hours=5.4 microgram
Quantity of substance delivered during 1 hour=0.1125 microgram
Quantity of substance delivered during 1 minute=0.001875 microgram (˜0.2 nanogram)
Quantity of substance delivered per vapor pulse (duration=1 second)=0.000031 (˜0.03 nanogram per second, or 30 picogram per second).
The average human respiratory rate at rest is about 15 breaths per minute.
The average breath duration is about 4 seconds.
The average duration of the inspiratory phase of each breath is about ⅓ of 4 seconds, therefore
The average duration of each inspiratory phase is about 1.3 seconds
Since one 1-second vapor pulse delivers 30 picogram of active substance,
In 1.3-second (duration of inspiratory rate) the quantity of active substance delivered is 39 picogram (˜40 picogram).
The delivery method used in the present study did not comprise pressurized air or any pressurized gas. All the recording procedures were done with the aid of standard, non-invasive electrodes attached to the surface skin using conductive paste, and caused minimal discomfort.
After completion of physiologic recordings and the modified DABS-70 (#3), all surface electrodes were removed and the subject went through an exit interview lasting 5 minutes. At this time the investigator recorded again the arterial blood pressure and also inquired the subject about his or her state of feelings, and also any possible adverse effect appearing during the study session.
Psychometric data analysis: To reduce the number of group comparisons and provide a meaningful framework for pre- to post-effects of the treatment, certain of the 67-items were grouped according to the following conceptual categories:
Individual mean scores were computed for each of the clusters for the pre- and post-experiment administration of the questionnaire. For example, responses to all of the items conceptualized as social warmth and friendliness for an individual subject prior to the experimental (or control) treatment were added and divided by 8 to produce a mean Social Warmth and Friendliness pre-test score for that individual. These mean scores were analyzed using a 2×2, mixed ANOVA with experimental vs. control as the grouping variable and pre- vs. post-scores as the repeated measure. Based on the a priori hypothesis that mean scores should not differentiate groups prior to experimental treatment but would be expected to differ following administration of the active substance, we examined group by repeated measures interactions for each of the ANOVAs.
In the planning stages of the study, a power analysis was conducted using data from a previous study (Grosser et al, 2000). The sample size of 38 (per gender group), given a large population effect, provided us with adequate power (0.80).
The mean respiratory rate (RF), heart rate (CF), electrodermal activity frequency (EDA), electromyogram (EMG), eye blinking (BR), body temperature (BT), and alpha, beta and theta frequency bands from the EEG recorded using the 20/20 international electrode placement chart, were computer measured and averaged using AcqKnowledge software (Biopac Systems). EEG spectral analysis was performed using the Fourier transform. The mean value of each physiologic parameter after exposure to control and pregna-5,20-dien-3β-ol were compared within gender group and between gender groups (Nmen=38; Nwomen=38) using ANOVA Post Hoc Tests (Statview, SAS).
The following five clusters were extracted from the modified DABS-70: Social Warmth and Friendliness, Arousal and Excitement, Sensuality, Personal Well-Being, and Negativity. The mean value of each cluster obtained during baseline and after exposure to control and pregna-5,20-dien-3β-ol were calculated and compared within gender group and between gender groups (Nmen=38; Nwomen=38) using ANOVA.
Seventy-six healthy subjects (38 men and 38 women), from a total of seventy-eight subjects recruited, complied with all the admission criteria stated in the research protocol and were admitted to the study. Each volunteer participated in one study session lasting 2 hours and 10 minutes where several physiologic parameters and behavioral changes were recorded before and after intranasal exposure to a small dose (12 ng) of airborne pregna-5,20-dien-3β-ol or control, delivered to the nasal passages from a perfumery grade smelling strip positioned on the upper lip. Pregna-5,20-dien-3β-ol was well tolerated by all volunteers of both gender groups and there were no reports of local or general adverse side effects recorded during the intervention and 24 hours after completion of the study session. All participating subjects completed the entire study.
As shown in Table 3 and
For women only, there was a significant difference in response for the Personal Well-Being cluster (active>control, p<0.002).
Responses to items within the Negativity cluster were not associated with being exposed to active versus control treatment.
In addition to the clusters described above, individual items of the modified DABS-70 inventory showed non-overlapping standard deviations between pregna-5,20-dien-3β-ol treatment and control treatment as follows; in men, pregna-5,20-dien-3β-ol exposure induced a significant increase in “Excited” and “Energetic;” in women, pregna-5,20-dien-3β-ol exposure induced a significant increase in “Excited,” “Loving,” and “Warm,” as shown in the Table 4.
Twenty minutes following the exposure to pregna-5,20-dien-3β-ol, via a paper tape placed on the upper lip of the subject, there were significant changes in physiologic parameters. The mean effects of pregna-5,20-dien-3β-ol and control on physiologic parameters are summarized in
Intranasal exposure to 12 ng pregna-5,20-dien-3β-ol was well tolerated by all volunteers and there were no adverse effects reported. There was no local nasal discomfort and none of the volunteers studied was able to smell pregna-5,20-dien-3β-ol. Clinical examination of the nasal passages at the end of the recording session did not reveal local lesions and/or inflammation of the mucosal lining of the nasal passages. Also, none of the subjects participating in the study reported having local or generalized discomfort during within 24 hours after the recording study, as revealed in a telephone interview the day after they participated in the study.
Pregna-5,20-dien-3β-ol decreased significantly mean respiratory rate in women (% ChangeRR Women=−16.03, P=0.0002) but not in men. Pregna-5,20-dien-3β-ol significantly decreased mean heart rate in men and women (% ChangeCF Men=−2.6, P=0.002; % ChangeCF Women=−3.0, P<0.002). Decreased cardiac rate remained within physiologic range and did not have hemodynamic repercussions as revealed by the absence of significant arterial blood pressure difference taken at the beginning of the study session and again during the exit interview.
Exposure to pregna-5,20-dien-3β-ol significantly increased the mean frequency of EDA events and this was significantly different from the effect of control in both gender groups (% ChangeEDA Men=44.458, P=0.013; % ChangeEDA Women=71.784, P=0.003). Body temperature did not change significantly from the effect of control after exposure to pregna-5,20-dien-3β-ol in either gender group.
The electromyogram (EMG) recorded from the peri-oral muscles (m. risorius), with the aid of surface skin recording electrodes, increased in both gender groups after pregna-5,20-dien-3β-ol as compared with the effect of control (% ChangeEMG Men=64.524, P=0.0055; % ChangeEMG Women=55.545, P=0.0001).
Blinking reflex (BR) also decreased in both gender groups after exposure to pregna-5,20-dien-3β-ol (% ChangeBR Men=−22.392, P=0.029; % ChangeBR Women=−31.859, P=0.003).
As shown in
This study shows that stimulation of nasal chemosensory receptors of human volunteers of both genders with a minuscule (nanogram) effective quantity of pregna-5,20-dien-3β-ol can affect behavior and physiologic parameters inducing changes suggestive of sexual arousal. All volunteers participating in the study did not perceive the active substance as an odor. The mechanism by which pregna-5,20-dien-3β-ol produces its behavioral effects is unknown. However, the physiologic decrease of heart rate and eye blinking has been found in other studies to be associated with pleasant psychological states (Tecee, 1992). Also, increased electrodermal activity (EDA), peri-oral muscle activity (EMG) and the Theta-EEG frequency band of the EEG have been described during erotic excitement and sexual excitation (Cohen et al, 1976).
Therefore, pregna-5,20-dien-3β-ol could be considered as a natural substance active in both genders through chemosensory receptors in the nasal passages that can induce a sexual arousal effect without producing olfactory awareness.
Electrophysiological recordings were conducted by exposure of subjects to pregna-1,4,20-trien-3-one and measuring the response as described in Example 6. The delivery of 29.6 picograms of pregna-1,4,20-trien-3-one was accomplished using the topical probe described in L. Monti-Bloch et al., (1991) J. Steroid Biochemistry & Molec.
