PYRROLIDINEANILINES

BACKGROUND OF THE INVENTION

The present invention relates to a pyrrolidineaniline that is useful as a progesterone receptor modulator.

Endometriosis is a disease characterized by the growth of endometrial tissue (called lesions) at extrauterine sites. This lesion attachment can result in pain, dysmenorrhea, dyspareunia, and infertility. It is estimated that greater than 80% of patients presenting with chronic pelvic pain are eventually diagnosed with endometriosis. The prevalence of the disease is about 7-10% of women of reproductive years with a familial association risk increase of 10-fold. Definitive diagnosis is only reached by laparoscopy, but typically there is about a ten year delay from disease onset to conclusive diagnosis. Consistent with their uterine origins, it is believed that the endometriotic lesions are hormonally dependent upon estrogen; consequently, therapies that functionally antagonize estrogen production or action, such as drugs containing progesterone receptor (PR) modulators, are efficacious in alleviating symptoms. Current therapeutic goals include reducing pain with anti-inflammatory agents and suspending the ovarian cycle using hormonal modulation drugs.

Another disease believed to be hormonally responsive to estrogen is uterine leiomyomas (fibroids), which appear as benign uterine smooth muscle tumors occurring primarily in women of reproductive age. Fibroids occur at rates of 20-25% and are the leading indication for hysterectomies. The most common symptoms are menorrhagia, pelvic pain/discomfort, bladder and bowel compression symptoms, and possibly infertility. Medical treatments for leiomyomas consist of those commonly prescribed for endometriosis, with treatments containing progesterone receptor modulators being most common due to safety, tolerability, ease of use and cost.

Most drug development has focused on modulation by full agonism or antagonism of progesterone receptors. For example, progestins are molecules that interact with progesterone receptor to activate or repress gene expression in target cells in a manner presumed to be progesterone-like. Though progestins are used in oral contraception, hormone therapy, and treatment of reproductive disorders, such as endometriosis and leiomyomas, these agents cause a number of adverse effects, including breakthrough bleeding, mood altering, acne, weight gain, and breast tenderness. Paradoxically, progesterone receptor antagonists such as mifepristone have been suggested as potential therapies, but the data are limited with few patients and no placebo-controlled randomized trials.

D. DeManno et al. (Steroids 68 (2003) 1019-1032), report that asoprisnil is a progesterone receptor modulator with mixed agonist/antagonistic activities. While the efficacy of the agent in treatment of endometriosis or fibroids is uncertain, early data from healthy female subjects indicate that the agent induces endometrial atrophy and amenorrhea, which suggests a predominantly progesterone receptor antagonist action in humans. Unfortunately, PR antagonists such as RU-486 tend to be abortifacient.

Accordingly, it would be desirable to discover a way to suppress estrogen-dependent endometriotic growth while reducing the systemic effects associated with current progesterone receptor modulating therapy.

Biological Assays
Abbreviations

Acquest/Biosystems is a multi-mode reader (FP reader); CHAPS refers to 3-cholamidopropyl-dimethylammonio 1-propanesulfonate; DTT refers to dithiothreitol.

PR Binding Assay—The assay was performed according to the manufacturers protocol (PR Competitor Assay Kit, Red—(Invitrogen—Product No. P2962)) with minor amendments. Briefly, 40 nM PR-Ligand Binding Domain, 2 nM Fluormone PL Red and 1 mM DTT were dissolved and mixed in Complete PR RED Buffer supplemented with 2 mM CHAPS. 10 μL of the mix was dispensed to each well of Greiner low volume plates, containing compounds at the required concentration. The plates were spun for 1 min at 200 g, covered to protect the reagents from light, and then incubated at room temperature for approximately 2 hours. Plates were read on an Acquest using a 530-25 nm excitation and 580-10 nm emission interference filter and a 561 nm Dichroic mirror.

Data Analysis

All data was normalized to the mean of 16 high and 16 low control wells on each plate. A four parameter curve fit of the following form was then applied

$y = \frac{a - d}{1 + {(\frac{x}{c})}^{b}} + d$

Where a is the minimum, b is the Hill slope, c is the XC50 and d is the maximum. Data is presented as the mean pIC₅₀with the standard deviation of the mean of n experiments.

Methods of Use

The compounds of the present invention are useful as modulators of progesterone receptors and may be useful in the treatment of disease associated with endometreosis and uterine fibroids. Thus, the present invention further relates to a method of treating a patient comprising administering to the patient an effective amount of a compound of formula I or a pharmaceutically-acceptable salt thereof or combination thereof to treat endometreosis or uterine fibroids.

Synthetic Schemes

Compounds of the present invention can be prepared, for example, in accordance with the following schemes. As used herein, Boc refers to t-butoxycarbonyl; DMSO refers to dimethyl sulfoxide; DMF refers to dimethylformamide; TFA refers to trifluoroacetic acid; DCE refers to dichloroethane; and Et₂O refers to diethyl ether.

In a first step, illustrated in Scheme 1, nucleophilic addition of pyrrolidine 1a to a phenyl fluoride forms aniline 1b or 1f. In the case where X=Cl, aniline 1b can be hydrogenated to form aniline 1c. Alternatively, reductive amination of aniline 1 h with ketone 1i yields secondary aniline 1j. Compounds 1b, 1c, 1f, or 1j can be further modified by treatment with strong base and electrophile to form the respective tertiary anilines and subsequent removal of the Boc protecting group under acidic conditions forms compounds 1e, 1g, and 1k.

Compounds 1e, 1g, and 1k can be further functionalized in accordance with Scheme 2:

Treatment of the pyrrolidine 1e with alkyl or benzyl bromides or t-butyl acrylate (Scheme 3) under basic conditions can afford the desired pyrrolidines 3a and 3b (Method E or F) while reaction of 1e with McSO₂Cl and pyridine yields the desired sulfonamide 3c (Method G).

Pyrrolidine 1b can be deprotected under acidic conditions to form 4a and the pyrrolidine nitrogen can be selectively functionalized to form 4b-4e (Scheme 4).

The aniline nitrogen can then be modified, for example, as shown in Scheme 5.

Scheme 6 illustrates the synthesis of various electrophiles that can be used to make compounds of the present invention:

It may be desirable to further derivatize a compound of the present invention. For example, thiophene bromide 7a can undergo a Suzuki reaction to yield 7b or the methyl ester 7c can be hydrolyzed to the acid 7d (Scheme 7). Moreover, as illustrated in Scheme 8, the ethyl ester 8a can be hydrolyzed under basic conditions to the acid 8b, which then can be reacted with LiAlH₄to yield the primary alcohol 8c.

Treatment of pyrrolidine 9a with PtO₂and H₂forms the desired compound 9b (Scheme 9). Moreover, as shown in Scheme 10, reaction of 10a or 10b under similar conditions yields the desired functionalized pyrrolidines 10c or 10d, respectively.

Examples

The following Examples are for illustrative purposes only and are not intended to limit the scope of the invention. The compounds from these Examples exhibit a pIC₅₀of greater than 5 (i.e., an IC₅₀of less than 10 μM). The phrase “IC₅₀of less than 10 μM” refers to an IC₅₀of less than 10 μM as measured using the PR binding assay described herein.
