Enalapril hepatotoxicity in the rat. Effects of modulators of cytochrome P450 and glutathione

The effects of modulators of cytochrome P450 and reduced glutathione (GSH) on the hepatotoxicity of enalapril maleate (EN) were investigated in Fischer 344 rats. Twenty-four hours following the administration of EN (1.5 to 1.8 g/kg), increased serum transaminases (ALT and AST) and hepatic necrosis were observed. Pretreatment of the animals with pregnenolone-16alpha-carbonitrile, a selective inducer of the cytochrome P450IIIA gene subfamily, enhanced EN-induced hepatotoxicity, whereas pretreatment with the cytochrome P450 inhibitor, cobalt protoporphyrin, reduced the liver injury. Depletion of hepatic non-protein sulfhydryls (NPSHs), an indicator of GSH, by combined treatment with buthionine sulfoximine (BSO) and diethyl maleate (DEM) produced marked elevations in serum transaminases by 6 hr after EN treatment. Administered on its own, EN decreased hepatic NPSH content and when combined with the BSO/DEM pretreatment, the liver was nearly completely devoid of NPSHs. Protection from EN-induced hepatotoxicity was observed in animals administered L-2-oxothiazolidine-4-carboxylic acid, a cysteine precursor. Together, these observations suggest the involvement of cytochrome P450 in EN bioactivation and GSH in detoxification. The results corroborate previous in vitro observations pertaining to the mechanism of EN-induced cytotoxicity towards primary cultures of rat hepatocytes. Although the doses of EN used in this study were far in excess of therapeutic doses, under certain circumstances, this metabolism-mediated toxicologic mechanism could form the basis for idiosyncratic liver injury in patients receiving EN therapy.

The application of anthraquinone-based triazenes as equivalents of diazonium salts in reaction with methylene active compounds

A series of polyfunctionalized anthraquinonehydrazones have been prepared using azo-coupling reaction between anthraquinone-based triazenes and methylene active compounds in acetic acid without a catalyst. The structures of new synthesized compounds were confirmed by their IR, LCMS,1H and 13C NMR spectroscopic data. Some of the synthesized compounds were screened for their in vitro anticancer activity according to US NCI protocols. Biological screening data led to the identification of 1-{N?-[3-(4-hydroxyphenyl)-4-oxo-2-thioxothiazolidin-5-ylidene]hydrazino}anthraquinone 3.4 as having antitumor activity on the non-small cell lung cancer NCI-H460 (GP = 13.25%) and colon cancer HCT-116 (GP = 13.69%) cell lines.

Design and synthesis of orally bioavailable 4-methyl heteroaryldihydropyrimidine based hepatitis B virus (HBV) capsid inhibitors

Targeting the capsid protein of hepatitis B virus (HBV) and thus interrupting normal capsid formation have been an attractive approach to block the replication of HBV viruses. We carried out multidimensional structural optimizations based on the heteroaryldihydropyrimidine (HAP) analogue Bay41-4109 (1) and identified a novel series of HBV capsid inhibitors that demonstrated promising cellular selectivity indexes, metabolic stabilities, and in vitro safety profiles. Herein we disclose the design, synthesis, structureactivity relationship (SAR), cocrystal structure in complex with HBV capsid proteins and in vivo pharmacological study of the 4-methyl HAP analogues. In particular, the (2S,4S)-4,4-difluoroproline substituted analogue 34a demonstrated high oral bioavailability and liver exposure and achieved over 2 log viral load reduction in a hydrodynamic injected (HDI) HBV mouse model.

Discovery of potent, isoform-selective inhibitors of histone deacetylase containing chiral heterocyclic capping groups and a N-(2-aminophenyl)benzamide binding unit

The synthesis of a novel series of potent chiral inhibitors of histone deacetylase (HDAC) is described that contain a heterocyclic capping group and a N-(2-aminophenyl)benzamide unit that binds in the active site. In vitro assays for the inhibition of HDAC1, HDAC2, HDAC3-NCoR1, and HDAC8 by the N-(2-aminophenyl)benzamide 24a gave respective IC50 values of 930, 85, 12, and 4100 nM, exhibiting class I selectivity and potent inhibition of HDAC3-NCoR1. Both imidazolinone and thiazoline rings are shown to be effective replacements for the pyrimidine ring present in many other 2-(aminophenyl) benzamides previously reported, an example of each ring system at 1 muM causing an increase in histone H3K9 acetylation in the human cell lines Jurkat and HeLa and an increase in cell death consistent with induction of apoptosis. Inhibition of the growth of MCF-7, A549, DU145, and HCT116 cell lines by 24a was observed, with respective IC50 values of 5.4, 5.8, 6.4, and 2.2 mM.
