Leukotriene D4 antagonists and 5-lipoxygenase inhibitors. Synthesis of benzoheterocyclic [(methoxyphenyl)amino]oxoalkanoic acid esters.

A series of novel benzoheterocyclic [(methoxyphenyl)amino]oxoalkanoic acid esters has been prepared. These compounds were tested as inhibitors of rat polymorphonuclear leukocyte 5-lipoxgenase (LO) in vitro and as inhibitors of leukotriene D4 (LTD4) and ovalbumin (OA) induced bronchospasm in the guinea pig (GP) in vivo. In general, inhibitory activity against 5-LO, LTD4, and OA was broadest for benzthiazole-containing analogues (benzthiazole greater than benzimidazole much greater than benzoxazole, benzofuran). The most potent 5-LO inhibitor, 4-[[3-(2-benzthiazolylmethoxy)-phenyl]hydroxyamino]-4-oxobutanoic acid methyl ester (7), had an IC50 of 0.36 microM. Compound 7, however, was inactive vs. OA. The most potent compound in vivo, 4-[[3-[(1-methyl-2-benzimidazolyl)methoxy]phenyl]-amino] -4-oxobutanoic acid methyl ester 4, inhibited both LTD4- and OA-induced bronchospasm by 83% and 60%, respectively, at 50 mg/kg intraduodenally. Compound 4 was studied in the Ames assay employing five strains of bacteria (TA1535, TA1537, TA1538, TA98, and TA100) with and without S-9 rat liver enzyme metabolic activation, and there was no significant number of reversions noted.

Nitrile-synthesizing enzyme: Screening, purification and characterization

Cyanide is known as a toxic compound for almost all living organisms. We have searched for cyanideresistant bacteria from the soil and stock culture collection of our laboratory, and have found the existence of a lot of microorganisms grown on culture media containing 10 mM potassium cyanide. Almost all of these cyanide-resistant bacteria were found to show beta-cyano-L-alanine (beta-CNAla) synthetic activity. beta-CNAla synthase is known to catalyze nitrile synthesis: the formation of beta -CNAla from potassium cyanide and O-acetyl-L-serine or L-cysteine. We found that some microorganisms were able to detoxify cyanide using O-methyl-DL-serine, O-phospho-L-serine and beta-chloro-DL-alanine. In addition, we purified beta-CNAla synthase from Pseudomonas ovalis No. 111 in nine steps, and characterized the purified enzyme. This enzyme has a molecular mass of 60,000 and appears to consist of two identical subunits. The purified enzyme exhibits a maximum activity at pH 8.5?9.0 at an optimal temperature of 40?50oC. The enzyme is specific for O-acetyl-L-serine and beta-chloro-DL-alanine. The Km value for O-acetyl-L-serine is 10.0 mM and Vmax value is 3.57 mumol/min/mg.

Dithiocarboxylic Acids, Dithiocarboxylic Esters, or Thiocarboxylic Amides by Reaction of Methylene-active Chloromethyl Compounds with Sulfur

With a mixture of sulfur and amine in DMF at room temperature halomethyl compounds (1,5-10) can be oxidized to give thiocarboxylic acids (2,11-16) and their derivatives (3,4,17-35).We studied this reaction in detail especially with chloroacetic derivatives (11-15) or chloromethyl heterocycles (16) formally derived from chloroacetic acid.The resulting thiooxalic acid derivatives (11-27) represent activated acids and very useful C2-synthons, especially for the synthesis of heterocycles.Oxidation in the presence of triethylamine leads to dithiocarboxylates (11-16) which can be alkylated to dithioesters (17-27) in high yields.As a rule, with different primary and secondary amines instead of tertiary amines these dithiocarboxylates or dithiocarboxylic esters can be transformed already at low temperatures to thioamides (28-35).

Metabolic characterization of meso-dihydroguaiaretic acid in liver microsomes and in mice

meso-Dihydroguaiaretic acid (MDGA) is a major component of Myristica fragrans and Machilus thunbergii that is traditionally used as a spice and for medicinal purposes. Despite reports of various biological activities exerted by MDGA, there is no information regarding its metabolic properties. The purpose of this study was to determine the metabolic stability and cytochrome P450 (CYP) inhibitory potential of MDGA, using pooled human liver microsomes (HLMs) to characterize its metabolic properties. In addition, pharmacokinetic analysis was performed in mice treated intravenously (5 mg/kg) or orally (20 mg/kg) with MDGA for comparison with our in vitro results. The half-life of MDGA in HLMs and mouse liver microsomes incubated with NADPH, UDPGA or NADPH plus UDPGA was 25.41 and 22.74, 0.39 and 0.20 or 0.28 and 0.22 min, respectively. In our pharmacokinetic study, MDGA rapidly declined in plasma and had low bioavailability, which was attributable to extensive metabolism by UDP-glucuronosyltransferases and CYPs. Among CYP isoforms, CYP2E1 activity was selectively inhibited by MDGA through a competitive inhibitory mode, with an inhibitory constant (Ki) value of 13.1 muM. These results suggest that MDGA can be used as a selective CYP2E1 inhibitor in vitro, which warrants evaluation of the pharmacological significance of MDGA-induced CYP2E1 inhibition.
