Certain hydroxy-phosphinyl-oxy-phenyl methyl-thiazolium hydroxide inner salts as PAF antagonists

BACKGROUND OF THE INVENTION
Platelet Activating Factor (PAF), 1-0-hexadecyl-/octadecyl-2-acetyl-sn-glyceryl-3-phosphorylcholine, is an ether lipid produced by a variety of different cell types. Recent studies [Snyder, F., Ann. Rep. Med. Chem., 17, 243 (1982); Pinckard, R. N., et. al., J. Adv. Inflammation Res., 4, 147 (1982); O'Flaherty, J. T., et. al., Clin. Rev. Allergy, 1, 353 (1983); Vargaftig, B. B., et. al., J. Trends. Pharmacol. Sci., 4, 341 (1983)] have shown PAF to be an important mediator of allergic disease. Included among the physiological processes in which PAF is implicated are aggregation of platelets, inflammation, smooth muscle contraction, pain and edema. PAF is implicated in asthma, respiratory distress syndrome, lung edema and other inflammatory and cardiovascular diseases.
The compounds of the present invention have proven to be specific inhibitors of the biological effects of PAF and are consequently useful for the treatment of asthma, anaphylactic, and septic shock, psoriasis, bowel necrosis, adult respiratory distress syndrome, transplant rejection, thrombosis, stroke, cardiac anaphylaxis and cancer.

The above patent and applications describe the preparation of alcohols of formulas 2 and 17 in both the racemic and optically active forms.

In addition to the synthetic methods discussed hereinabove, many of the methods and procedures described in the aforementioned U.S. Patent and copending applications are applicable to the preparation of the compounds of this invention by one skilled in the art.
The compounds were tested for pharmacological activity as described in the following tests.
Platelet Activating Factor Antagonism in vitro
Platelet activating factor (PAF) compounds were evaluated as PAF receptor antagonists in vitro by measuring inhibition of PAF induced platelet aggregation. Platelet aggregation was measured by a modification of the method of A. Wissner, et. al., J. Med. Chem., 27, 1174, 1984.
Approximately 120-240 ml of blood were collected by cardiac puncture from unanesthetized male New Zealand White rabbits (Whaley's Summit View Farms, Belvedere, N.J.) with the use of 3.2% sodium citrate anticoagulant (1 part of citrate/10 parts of blood). All syringes and pipets were plastic. The blood was gently mixed and immediately centrifuged at 800 rpm for 10 minutes at room temperature to recover the platelet rich plasma (PRP). Platelet poor plasma (PPP) was prepared by centrifuging PRP at 2800 rpm for 10 minutes at room temperature.
Dilutions (1:3000) of PRP in Isoton diluent were made and platelet counts were determined on a Coulter Thrombocounter which was standardized with platelet reference standards (Interscience Platelet Control, Portland, Oreg.). PRP platelet counts were adjusted to 500,000 platelets/.mu.l by the addition of PPP.
L-PAF was obtained from Calbiochem. A stock solution of 1-2 E-3M was prepared in 10% ethanol in water and serial working dilutions were made using phosphate buffered saline (PBS). 1-2 E-3M stock solutions of test compounds were prepared in 100% methanol and serially diluted in PBS. All solutions were made up in plastic tubes, stored on ice and protected from heat and light. Solutions were prepared fresh or frozen at -20.degree. C. and used within 48 hours.
Incubation mixtures consisted of 400 .mu.l PRP, 50 .mu.l of PBS diluent or test compound and 50 .mu.l of PAF agonist. More specifically, 400 .mu.l of PRP was stabilized in a cuvette for 1-2 minutes at 37.degree. C. in the aggregometer to achieve a stable baseline, then 50 .mu.l of PBS or test compound, was added and incubated for 5 minutes before addition of the challenge concentration of PAF (final concentration of 5E-8M or 1E-7M, as determined from the dose response curve for PAF for that experiment). Aggregation was monitored for 5 minutes. Samples containing test compound or diluent were run simultaneously for comparison. Test compounds were initially evaluated at a screening concentration of 1E-5M. Those producing .gtoreq.50% inhibition of the magnitude of aggregation were then reevaluated in a dose response fashion (final concentrations 1E-7M to 5E-5M) and IC50 values were determined.
K.sub.i values were also calculated in some cases from ##EQU1## where K.sub.i =inhibitory constant
IC.sub.50 =molar concentration of test compound which gives 50% inhibition
[PAF]=molar concentration of PAF used as challenges
EC.sub.50 =molar concentration of PAF which gives 50% of maximal aggregation.
The recording equipment consisted of single or dual channel Chronolog aggregometers connected to dual channel 10MV full scale deflection Omniscribe chart recorders (Houston Instruments). The chart recorders were calibrated daily with the use of a suspension of Bio-Rad latex beads (S-X 12 400 mesh) which had a density slightly greater than rabbit PRP. The bead suspension was used to set the 0% light transmission mark and clear water was used to set the 100% light transmission mark. These limits defined a full scale deflection. The aggregation traces were analyzed by a digitizing method (C. Kohler and B. Zoltan, J. Pharm. Methods, 12, 113, 1984) with x, y coordinate data stored in a computer file. A suitable program computed parameters of interest such as the magnitude of aggregation.
In some experiments, washed platelets were used instead of PRP. Washed platelet suspensions were prepared as follows. PRP was centrifuged at 2800 rpm for 10 minutes to obtain PPP and a platelet pellet. The pellet was gently suspended and washed in calcium free, albumin free Tyrode's buffer, pH 6.3. The suspension was recentrifuged and the washed pellet was resuspended in normal Tyrodes' buffer (with calcium, but albumin free), pH 7.4. Platelet counts were adjusted to 500,00 platelets/.mu.l.
The results of this test on representative compounds of this invention appear in Table I, II, and III.

Inhibition of PAF Induced Vascular Permeability Change in Guinea Pig Skin
Platelet Activating Factor (PAF) given intradermally, increases capillary permeability, and plasma proteins (e.g. albumin) leak from the vascular space into the interstitial fluids of the skin. If the albumin has been previously stained with Evans' blue dye, the lesion area can be visualized as a blue spot in the skin. A specific PAF antagonist inhibits the development of increased capillary permeability caused by PAF and reduces the leakage of proteins into the skin. Test compounds were evaluated for non-specific effects by monitoring their ability to inhibit or reduce a histamine induced increase in capillary permeability.
Test Solutions were prepared as follows: Evans' Blue Dye (Sigma E2129) was dissolved in saline to yield a 0.1% w/v solution. A 2 mg/ml stock chloroform solution of PAF (1-phosphotidyl, acetyl-O-alkyl; Sigma P9525) was diluted in saline to give final concentrations of 500 and 250 ng/ml. Saline dilutions were made fresh for each test. Histamine diphosphate solutions (Sigma H7375) were prepared by dissolving 10 mg in 100 ml of saline and diluting to 20 .mu.g/ml with saline. Test compounds were dissolved in ethanol at 10 mg/ml and stored at -70.degree. C. Injection mixtures were made by placing 10 .mu.l of test compound solution into 1.0 ml of either the PAF solutions or the histamine solution.
The animals used were Hartley strain guinea pigs weighing 250-350 g, maintained with food and water ad libitum. The animals were shaved on their back and hind feet one day before use.
Each guinea pig was given an intravenous injection of 2 ml of Evans' blue dye solution into a foot vein. Immediately after, a series of six intradermal injections of 0.1 ml each were given, three on each side of the animal. They were: PAF 50 ng (0.1 ml of a 500 ng/ml solution); PAF 25 ng; and histamine diphosphate 2 .mu.g. The left side injections contain 10 .mu.g of test compound while the right side contain an equivalent amount of the ethanol vehicle to serve as a control.
Thirty minutes later the animals were killed by cervical dislocation and the skin reflected from the back. The lesion areas were approximated as the product of the largest diameter and normal diameter both in mm.
A test compound was considered active if it caused a 50% or greater reduction in the lesion area of the PAF injection which produced a control lesion closest to 100 mm.sup.2 without altering the histamine induced spot. The results appear in Table IV.
Inhibition of PAF Induced Vascular Permeability Change in Mouse Skin
The rationale for this test is similar to the coinjection test in guinea pigs; however, the test compound was given intraperitoneally rather than coinjected.
Test solutions were prepared as follows: An 80 .mu.g portion of PAF was dissolved in 40 ml of saline to yield a concentration of 2000 ng/ml. A 10 mg portion of histamine diphosphate was dissolved in 100 ml of saline to yield a concentration 100 .mu.g/ml. Test compounds were dissolved in saline and given intraperitoneally (20 mg/kg) 1/2 hour before intradermal challenge with PAF or histamine.
The animals used were Hilltop ICR mice, shaved on their flanks one day before use. The mice were randomly assigned to treated and control groups and were given test compound or saline 1/2 hour before challenge. Each mouse was injected via a tail vein with 0.25 ml of 0.05% Evans' blue dye immediately before the PAF or histamine intradermal injections were made (0.05 ml each), one per side.
Thirty minutes later the animals were killed and the lesions areas measured as described above. Lesion areas in treated animals were expressed as a percent of the control lesions and an ED.sub.50 (mg/kg) was calculated from an arcsine area vs. log dose transform. The results appear in Table IV.
PAF Induced Lethality in the Mouse
Test compounds were evaluated for their ability to prevent death induced by an intravenous injection of a lethal dose of PAF.
ICR mice were given test compounds intraperitoneally as described under Inhibition of PAF Induced Vascular Permeability Change in Mouse Skin, 1/2 hour before an intravenous dose of 100 .mu.g/kg PAF in saline. One hour later the number of dead mice were recorded. Protection was expressed as percent survivors in treated group/percent survivors in control group. The results appear in Table IV.

The residue was added to a mixture 200 ml of tetrahydrofuran and 200 ml of 0.5N sodium acetate and stirred for 2.5 hours. The tetrahydrofuran was removed, the aqueous remainder acidified with dilute hydrochloric acid and extracted three times with ether. the extracts were combined, washed with brine, dried over magnesium sulfate, and evaporated giving 10.7 g of the desired product as an oil.
EXAMPLE 49
3-[[3-[[[3-[3-(dodecyloxy)-2-methylphenoxy]-2-ethoxypropoxy]hydroxyphosphinyl]oxy]phenyl]methyl]-5 -methyl-thiazolium, hydroxide, inner salt
In a pressure bottle a mixture of 5.2 g of 3-(bromomethyl)phenyl 2-[3-dodecyloxy)-2-methylphenoxy]-2-ethoxyethyl phosphate from Example 48, 4.81 g of 5-methylthiazole and 40 ml of toluene was stirred under argon at 75.degree. C. for 4 hours. The solvent was evaporated and the residue stirred with 10 g of Amberlite.RTM. IR45 ion exchange resin in 70 ml of methanol for 15 minutes. The mixture was filtered, evaporated and the residue purified by chromatography. The produce was precipitated from ether, giving 3.0 g of the desired product as a white powder.
