- Synthesis and biological evaluation of piperazinyl heterocyclic antagonists of the gonadotropin releasing hormone (GnRH) receptor
-
Antagonism of the gonadotropin releasing hormone (GnRH) receptor has resulted in positive clinical results in reproductive tissue disorders such as endometriosis and prostate cancer. Following the recent discovery of orally active GnRH antagonists based on a 4-piperazinylbenzimidazole template, we sought to investigate the properties of heterocyclic isosteres of the benzimidazole template. We report here the synthesis and biological activity of eight novel scaffolds, including imidazopyridines, benzothiazoles and benzoxazoles. The 2-(4-tert-butylphenyl)-8-(piperazin-1-yl)imidazo[1,2-a]pyridine ring system was shown to have nanomolar binding potency at the human and rat GnRH receptors as well as functional antagonism in vitro. Additional structure-activity relationships within this series are reported along with a pharmacokinetic comparison to the benzimidazole-based lead molecule.

- An application of the stille coupling for the preparation of arylated phthalonitriles and phthalocyanines
-
The substituted phthalonitriles 4-phenylphthalonitrile (2a), 4-(2,5-dimethoxyphenyl)phthalonitrile (2b) and 2-(3,4-dicyanophenyl)-4-methylpyridine (2c) have been prepared in good yields from 4-iodophthalonitrile 3, the synthesis of which is also discussed, using the Stille coupling method. Such phthalonitriles are precursors for phthalocyanines with the possibility of biphenyl-like orientation of a peripheral substituent with respect to the macrocycle ring plane. As an example, 2b was used in the preparation of tetra(dimethoxyphenyl)phthalocyanine 1a. Both 1a and the corresponding zinc(II) complex show good solubility in non-polar solvents such as dichloromethane.

- Synthesis of Mercapturic Acid Derivatives of Putative Toxic Metabolites of Bromobenzene
-
The synthesis and characterization of nine isomerically defined S-arylmercapturic acids of interest in connection with the metabolism of the model hepatotoxin bromobenzene is described.Included are three S-(bromophenyl)-, two S-(bromohydroxyphenyl)-, and three S-(bromodihydroxyphenyl)mercapturic acids of defined substitution pattern.In addition, several related compounds with two or no bromine atoms are described.These syntheses depend on two basic methods, 1,4-addition of various arene thiols to acetamidoacrylic acid or the 1,4-addition of N-acetyl-L-cysteine to various benzoquinone derivatives.In addition, we describe a method for efficient conversion of the mercapturic acids to thioanisole derivatives, regioisomers of which can be separed and detected at low levels by capillary gas-liquid chromatography.
