Description: 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 Platelet Activating Factor 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.

DETAILED DESCRIPTION OF THE INVENTION The preparation of compounds of this invention encompassed by Formulas IA-C is described hereinbelow in Flowsheet A, wherein n, X, R₁ and R₅ are described hereinabove. The moieties -CH₂-J and -CH₂-Y' represent substituents of the aromatic ring which are meta or para to the phosphate group wherein J is a leaving group such as the halogens chlorine or bromine and Y' is a nitrogen containing heterocycle which can be wherein R₄ and R₅ are as described hereinabove. According to the sequence of reactions outlined in Flowchart A, the phenol or alcohol 2 is treated with an equivalent of the phosphorus reagent 3 in the presence of a base such as triethylamine in an inert solvent such as carbon tetrachloride to give, after hydrolysis of the resulting intermediate in a buffered solvent system such as tetrahydrofuran-water-sodium acetate, the phosphate 4 . The reaction of 4 with a large excess of a nitrogen containing heterocycle in an inert solvent such as toluene at 50°-150°C gives the compounds of this invention represented by formula IA. These compounds are obtained as internal salts except when A is an imidazole moiety. In those cases where the compounds contain an imidazole ring (Formula IB), the imidazole moiety can be further alkylated with an excess of alkyl halide by heating in an inert solvent such as toluene to give the internal salts IC. The preparation of compounds of this invention encompassed by formulas ID-IF is described hereinbelow in Flowchart B wherein R₄, Y′, X, R₁, and R₅, and J are as defined hereinabove. According to the sequence of reactions outlined in Flowchart B, the phenol 2 is treated with an equivalent of the phosphorus reagent 5 in the presence of a base such as triethylamine in an inert solvent such as carbon tetrachloride to give the cyclic phosphate 6 . The reaction of 6 with a large excess of a nitrogen containing heterocycle in an inert solvent such as toluene at 50°-150°C gives the compounds of this invention represented by formula ID. These compounds are obtained as internal salts except when Y' is an imidazole moiety. In those cases where the compounds contain an imidazole ring (formula IE), the imidazole moiety can be further alkylated with an excess of alkyl halide by heating in an inert solvent such as toluene to give the internal salts IF. The phosphorous reagents represented by formulas 7a and 7b needed to prepare some of the compounds of this invention are prepared as described hereinbelow in Flowsheet C and in U.S. Patent 4762942 (1988). According to the reaction outlined in Flowsheet C, the phenols 8a or 8b are reacted with phosphorous oxychloride and at least one equivalent of an amine base such as triethylamine in an inert solvent such as carbon tetrachloride to give the phosphorous reagents 7a and 7b . The cyclic phosphorous reagents represented by formula 9 needed to prepare some of the compounds of this invention are prepared as described hereinbelow in Flowsheet D wherein R₁ is as defined hereinabove. According to the reactions outlined in Flowsheet D, the hydroxy phenol 10 is treated with an equivalent of phosphorous trichloride in an inert solvent such as ether in the presence of at least two equivalents of pyridine to give compound 11 . Oxidation of 11 with a dry stream of oxygen in benzene then furnishes the phosphorous reagent 9 . The substituted phenols and hydroxy naphthalenes of Formula 12 needed to prepare the compounds of this invention can be prepared as described in the following U.S. patents: 4,697,031; 4,699,990 and 4,640,913 and as described hereinbelow in Flowsheet E , wherein R₆ represents one or more substituents which may occupy any position and are selected from the group consisting of hydrogen, -R₂, trifluoromethyl, and fluorine wherein R₂ is as described hereinabove, and R₇ is C₁-C₂₅ alkyl or C₁-C₂₅ alkenyl. J' is chlorine, bromine or iodine. According to the sequence of reactions outlined in Flowsheet E , a substituted bromo anisol 10 is reacted with magnesium in tetrahydrofuran to form the Grignard reagent which in turn is reacted with an alkyl halide in the presence of Li₂CuCl₄. The resulting methyl ether 11 is cleaved to the desired phenol using boron tribromide in an inert solvent such as methylene chloride. An identical sequence of reaction can be applied to furnish substituted hydroxy naphthalenes needed to prepare some of the compounds of this invention. The substituted phenols and hydroxy naphthalenes of Formula 14 needed to prepare the compounds of this invention can be prepared as described in the following U.S. patents: 4,697,031; 4 697 031 4,699,990 and 4,640,913 and as described hereinbelow in Flowsheet F wherein R₂ and J' are as hereinabove defined and R₇ is C₁-C₂₅ alkyl and C₁-C₂₅ alkenyl. According to the sequence of reactions shown in Flowsheet F, treatment of the dihydroxy compound 13 with sodium hydride in an inert solvent such as dimethylformamide in the presence of an alkyl halide produces the monoalkylated product 14 which can readily be separated from the unreacted 13 and the dialkylated product by a combination of distillation and chromatography. In those cases where two isometric monoalkylated products result, they can be separated using chromatographic procedures. An identical sequence of reactions can be applied to the synthesis of the hydroxy naphthalenes needed to prepare the compounds of this invention. Some of the phenols and hydroxy naphthalenes that can be used to prepare the compounds of this invention are listed hereinbelow in Table I. The compounds of this invention were tested for pharmacological activity as described in the following tests. Platelet Activating Factor Antagonism In Vitro Test compounds were evaluated as Platelet Activating Factor receptor antagonists in vitro by measuring inhibition of Platelet Activating Factor induced platelet aggregation. Platelet aggregation was measured by a modification of the method described in 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, NJ) 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 10-15 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, OR). PRP platelet counts were adjusted to approximately 400,000-500,000 platelets/µl 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 or 100% methanol 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°C and used within 48 hours. Incubation mixtures consisted of 400 µl PRP, 50 µl of PBS diluent or test compound and 50 µl of PAF agonist. More specifically, 400 µl of PRP was stabilized in a cuvette for 1-2 minutes at 37°C in the aggregometer to achieve a stable baseline, then 50 µl of PBS or test compound, was added and incubated for 5 minutes before addition of the challenge concentration of Platelet Activating Factor (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 ≥ 50% inhibition of the magnitude of aggregation were then reevaluated in a dose response fashion (final concentrations 1E-8M to 5E-5M) and IC₅₀ values were determined from the dose response curve. The recording equipment consisted of a dual channel Chronolog aggregometer connected to a dual channel 10MV full scale deflection Omniscribe chart recorder (Houston Instruments). The chart recorder was 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 rabbit platelets were used instead of rabbit PRP. Washed platelet suspensions were prepared as follows. Rabbit 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 500,000 platelets/µl. The challenge concentration of Platelet Activating Factor used for washed platelet experiments was 5E-9M. In some experiments, human PRP was used instead of rabbit PRP. Blood from healthy volunteers was collected in Vacutainers® containing the Na citrate diluent and processed in a manner similar to rabbit blood to obtain the PRP. For these experiments, the challenge concentration of Platelet Activating Factor was 1E-6M. The results of tests on representative compounds of this invention appear in Tables III, IV, V. Data are in Molar IC₅₀ values (concentration which produces 50% inhibition) in rabbit platelet rich plasma. The challenge concentration of 1-Platelet Activating Factor) was 5E-8M. Numbers in parentheses refer to number of experiments. Data are molar IC₅₀ values (concentration which produces 50% inhibition) in washed rabbit platelets. The challenge concentration of PAF was 5E-9M. Numbers in parentheses refer to number of experiments. Data are molar IC₅₀ values (concentration which produces 50% inhibition) in human platelet rich plasma. Numbers in parentheses refer to numbers of experiments. In Vivo Tests for Platelet Activating Factor A. Guinea Pig Vascular Permeability (Skin Lesion) Model Platelet Activating Factor produces a rapid increase in capillary permeability and intradermal injection of PAF causes leakage of plasma proteins into the extracellular space. If these proteins are previously tagged with Evan's blue dye, a blue spot develops in the skin. A Platelet Activating Factor antagonist will reduce the leakage and reduce the size of the spot. Specificity of the Platelet Activating Factor antagonist can be determined by also checking the response to other agonists such as histamine. The initial in vivo test uses coinjection of test compound and Platelet Activating Factor agonist in the guinea pig skin model. The following protocol describes the coinjection methodology. Hartley strain guinea pigs (300-400gm) were maintained with food and water ad lib. The backs and hind feet of the animals were shaved 1 day before use. Platelet Activating Factor (Sigma) P9525) was dissolved in saline at 500 ng/ml and diluted 1:1 to make a 250ng/ml solution. Histamine diphosphate (Sigma H7375) was dissolved in saline at 25ug/ml. Test compounds were dissolved in ETOH at 10mg/ml. The injection solutions were made by mixing 10ul of test compound solution or ETOH into 1ml of PAF or histamine solution. The guinea pigs were given 2ml of Evan's Blue dye (0.5%w/v) in saline via a foot vein. Immediately after, six 0.1ml intradermal injections were made into the back of the guinea pig, 3 per side. The left side was injected with 50ng PAF+10ug test compound (0.1ml of 500ng/ml PAF+100ug/ml test compound), 25ng PAF+10ug test compound, and 2.5ug histamine +10ug test compound. The right side was injected with the same pattern of the ETOH control solutions. In addition, a separate group of animals received 10ug of test compound in saline as a control for direct test compound effects. Twenty minutes later, the animals were killed by a blow to the head and the skin reflected from the back. The blue lesion areas (due to increased vascular permeability) were estimated as the product of the longest and shortest diameters. A compound was considered active if it reduced the Platelet Activating Factor induced lesion by 50% or more without altering a histamine induced lesion. Those compounds which were active by the coinjection route were examined by intraperitoneal administration. Two protocols were used, the first with both Platelet Activating Factor and histamine as agonists; the second used 6 concentration levels of Platelet Activating Factor. Protocols were similar to the methods described above, except ETOH was eliminated from the solutions. In protocol I, the Platelet Activating Factor was administered by intradermal injections at 50, 25, and 12.5ng/site and histamine at 2, 1, and 0.5ug/site. In protocol II, six sites were injected with PAF at 50, 25, 12.5, 6.25, 3.125, and 1.56 ng/site. For each protocol, the methods were as described above. A compound was considered active at the dose used if it significantly reduced the PAF lesions without altering the histamine response. B. Platelet Activating Factor Induced Lethality in Mice Platelet Activating Factor given I.V. to mice causes an immediate hypotensive shock leading to death in 1 hour or less. Compounds were given intraperitoneally or P.O. at various times before the Platelet Activating Factor challenge. Animals alive after 2 hours were counted and the activity of test compounds expressed as % survival corrected for any control (saline treated) animals which survived the Platelet Activating Factor challenge. Results of this assay appear in Table VI. C. Endotoxin Induced Hypotension in Rats Rats given LPS I.V. demonstrates a profound hypotension; to the extent that this is a Platelet Activating Factor induced phenomena, a PAF antagonist should restore normal blood pressure. Bacterial cell wall lipopolysaccharide from E. coli strain O111:B4 (Sigma #L-2630) was dissolved in saline at a concentration of 3.75mg/ml and administered to rats at 15mg/kg I.V. Test compounds were dissolved in saline at 1mg/ml, diluted to 10ug/ml, and injected intraarterially at 1ml/kg (10ug/kg). Male wistar strain rats were obtained from Charles River Labs and maintained according to ALAC standards. They were anesthetized with 30mg/kg pentobarbital ip with supplementation as needed. The throat was opened, the left carotid artery was cannulated with PE-10 tubing and the trachea cannulated with 0.100 O.D. tubing. Ventilation was maintained by a Harvard Apparatus small animal pump at a rate sufficient to nearly abolish spontaneous respiration. The mean arterial pressure was measured using a Statham PM23 transducer and displayed on a Grass model 7 polygraph. Endotoxin was given intravenously or intraarterially if the tail veins had collapsed. After 5 minutes, the test compound was given intraarterially since the tail veins generally collapsed after endotoxin administration. Results are expressed as the % reversal of the fall in mean arterial pressure as shown in Table VII. D. Endotoxin Induced Shock and Mortality in Mice Endotoxin administration produces a shock state characterized by hypotension, neutropenia, thrombocytopenia and death. Platelet Activating Factor administration mimics the signs and symptoms of endotoxin induced shock and death and endotoxin also induces the release of Platelet Activating Factor. Therefore, the effects of endotoxin should be blocked with a PAF antagonist. Male Balb/c mice (approximately 20g) were obtained from Charles River Laboratories and used after a one week acclimation period. Animals were injected (iv or ip) with test compound at different time intervals prior to the iv or ip injection of endotoxin. Sigma E. Coli endotoxin, 0111:B4, phenol extraction, catalog # L2630 was used for these studies. The endotoxin dose was determined from dose-response titrations and adjusted to a dose that was lethal for 90% (LD₉₀) of the mice within a 24 hour period. This LD₉₀ value was approximately 50mg/kg iv and 80mg/kg ip. The number of survivors in each group (control or treated with test compound) was recorded after 24, 48 or 72 hours and the treated groups (receiving test compound and endotoxin) was compared with the untreated, control group (receiving endotoxin only). The test compounds, known to be Platelet Activating Factor antagonists from in vitro platelet aggregation studies, were active in reducing 24 hour mortality when administered ip prior to a lethal ip injection of endotoxin (Table VIII). The test compounds (PAF antagonists) were also efficacious when administered iv prior to a lethal iv injection of endotoxin (Table IX). E. Endotoxin Induced Hemorragic Lesions in Rats Endotoxin induces an immediate, profound hemorragic lesion in the gut of rodents. 3-[[3-[[hydroxy[2-methoxy-3-(tetradecyloxy)phenoxy]phosphinyl]oxy]phenyl]methyl]-5-methyl-thiazolium, hydroxide, inner salt given IP one hour before challenge at doses as low as 1/2 mg/kg is able to reduce or eliminate the damage produced by IV LPS. Results of this assay appear in Table X. One of the main sites of LPS induced pathology in the rat and guinea pig is the gut, particularly the duodenum, small intestine and cecum. After LPS exposure hemorragic lesions develop within a few minutes and can involve most of the lumenal surface. The extent of these pathologies can be quantitated histologically or by measuring the amount of plasma proteins that have leaked into the lumen. The second method is much faster and can detect damage in the junctions between capillary or intestinal epithelial cells before gross lesions have developed. Hot tags have shown plasma leakage after LPS challenge using radiolabeled albumin as the probe. In our assay we have chosen to use a non-radioactive tagging method in which plasma albumin is labeled with Evan's blue dye and the lumenal leakage is determined spectrophotometricly. The data available now indicates that LPS acts by inducing the synthesis and release of tumor necrosis factor (TNF) which in turn causes synthesis and release of platelet activating factor. PAF seems to be the major cytotoxic agent involved in many of the pathophysiologic changes seen in endotoxic shock and these changes can be induced by direct injection of PAF. Therefore a PAF antagonist ought to prevent the intestinal damage brought on by injection of LPS. We have demonstrated that 3-[[3-[[hydroxy[2-methoxy-3-(tetradecyloxy)phenoxy]phosphinyl]oxy]phenyl]methyl]-5-methyl-thiazolium, hydroxide, inner salt prevents the gut manifestations of endotoxin shock and does so at doses as low as 0.25 mg/kg in rats. Chemicals Evan's blue dye: Sigma e-2129, made as a 1%w/v solution in saline which was filtered and kept refrigerated. Platelet activating factor (PAF) was obtained from Sigma, P-9525. This is supplied as a chloroform solution at 2 mg/ml and was diluted in the dye solution to 2.5 µg/ml. For each experiment fresh 3-[[3-[[hydroxy[2-methoxy-3-(tetradecyloxy)phenoxy]phosphinyl]oxy]phenyl]methyl]-5-methyl-thiazolium, hydroxide, inner salt was sonicated into saline. Biologicals Endotoxin: Lipopolysaccharide (LPS) isolated from E. coli strain 0111:b4 by phenol extraction was obtained from Sigma, L-2630. LPS solutions were made fresh for each experiment. Animals Male Wistar rats, obtained from Charles River, weighing 160-225 gm were maintained in accordance with ALAC standards for at least one week before use. Protocols Food was withheld from the animals for 18 hours before the experiment to clear the intestine. The rats were dosed with 3-[[3-[[hydroxy[2-methoxy-3-(tetradecyloxy)phenoxy]phosphinyl]oxy]phenyl]methyl]-5-methyl-thiazolium, hydroxide, inner salt or saline ip, 4 ml/kg, 1/2 hour before challenge with 25 or 50 mg/kg LPS in the 1% dye at 10 ml/kg. One hour after the LPS insult the animals were sacrificed and the duodenum and initial 6-7 cm of the jejunum isolated. This segment was lavaged with 2 ml of normal saline with the fluid flowing into polyethylene tubes. The lavageate frequently contained mucous and in order to free the stained albumin the samples were sonicated vigorously and then centrifuged to clarify the fluid. The amount of dye was determined spectrophotometrically, using a Vmax microtiter plate reader using the end point mode at 600nM. Discussion The most obvious damage seen in examination of rodents given endotoxin is a massively swollen caecum and hemorragic lesions in the stomach and small intestine. Similar pathology is also seen in humans with systemic septic shock. The relative importance of direct capillary damage by PAF vs ischemia-reperfusion damage brought on by the profound hypotension induced by LPS is unknown. However, 3-[[3-[[hydroxy[2-methoxy-3-(tetradecyloxy)phenoxy]phosphinyl]oxy]phenyl]methyl]-5-methyl-thiazolium, hydroxide, inner salt has demonstrated very potent protection against the end point of gut pathophysiology. Direct observation of the intestinal tract of LPS challenge control animals and 3-[[3-[[hydroxy[2-methoxy-3-(tetradecyloxy)phenoxy]phosphinyl]oxy]phenyl]methyl]-5-methyl-thiazolium, hydroxide, inner salt protected animals revealed that the protected animals had nearly normal appearing guts. Blind testing became difficult as virtually all the control animals had severe diarrhea while the 3-[[3-[[hydroxy[2-methoxy-3-(tetradecyloxy)phenoxy]phosphinyl]oxy]phenyl]methyl]-5-methyl-thiazolium, hydroxide, inner salt animals had little or none. The overall activity of 3-[[3-[[hydroxy[2-methoxy-3-(tetradecyloxy)phenoxy]phosphinyl]oxy]phenyl]methyl]-5-methyl-thiazolium, hydroxide, inner salt was significant with activity seen at doses as low as 1/2 mg/kg IP.

For oral therapeutic administration, these active compounds may be incorporated with excipients and used in the form of tablets, capsules, elixirs, suspensions, syrups and the like. Such compositions and preparations should contain at least 0.1% of active compound. The percentage of the compound in these compositions may, of course, be varied and may conveniently be between about 2% to about 60% of the weight of the unit. The amount of active compound in such therapeutically useful compositions is such that a suitable dosage will be obtained. Preferred compositions according to this invention are prepared so that an oral dosage unit contains between about 1 and 250 mg of active compound. The tablets, capsules and the like may also contain a binder such as gum tragacanth, acacia, corn starch or gelatin; excipients such as dicalcium phosphate; a disintegrating agent such as corn starch, potato starch, alginic acid; a lubricant such as magnesium stearate; and a sweetening agent such as sucrose, lactose or saccharin. When the dosage unit form is a capsule, it may contain, in addition to materials of the above type, a liquid carrier such as a fatty oil. Various other materials may be present as coatings or to modify the physical form of the dosage unit. For instance, tablets may be coated with shellac, sugar or both. A syrup or elixir may contain, in addition to active ingredient, sucrose as a sweetening agent, methyl and propylparabens as preservatives, a dye and flavoring such as cherry or orange flavor. These active compounds may also be administered parenterally. Solutions or suspensions of these active compounds can be prepared in water suitably mixed with a surfactant such as hydroxypropylcellulose. Dispersions can also be prepared in glycerol, liquid polyethylene glycols and mixtures thereof in oils. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms. The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. In all cases, the form must be sterile and must be fluid to the extent that easy syringability exists. It must be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms such as bacterial and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g. glycerol, propylene glycol and liquid polyethylene glycol), suitable mixtures thereof, and vegetable oils.
