Pharmacological evaluation of prazosin- and doxazosin-related compounds with modified piperazine ring

New doxazosin-related compound (1-3) with a N,N’-dimethyl alkanediamine chain replacing the piperazine ring, have been synthesized and their pharmacological properties have been tested together with some prazosin analogues (4-8) bearing either a similar structural modification or a substituted piperazine moiety. In the in vitro study, on alpha1- and alpha2-adrenoceptors of rat vas deferens tissues, 1-3 displayed high alpha1-antagonist activity, 2 and 3 being equipotent to doxazosin but markedly less selective in respect to alpha2-adrenoceptors. Replacement of the piperazine ring with an alkanediamine chain resulted in a strong fall in alpha1-selectivity, owing to increased alpha2-antagonist activity, as in the prazosin-related series. In in vivo studies, the antihypertensive activity of tested compounds was investigated on spontaneously hypertensive rats (SHR) following both intragastric (IG) and intraperitoneal (OP) administration. Among the tested compounds, 7 and 8, which conserved a substituted piperazine ring, proved the most interesting drugs displaying a marked hypotensive effect. The other prazosin- and doxazosin-related compounds, in which an alkanediamine chain replaced the piperazine nucleus, showed an antihypertensive activity markedly lower than that of parent compounds, prazosin (CAS 19216-56-9) and doxazosin (CAS 74191-85-8), although a high alpha1-antagonist activity in in vitro tests was conserved. These results suggest that the piperazine ring of the prazosin- and doxazosin-related compounds, although not crucial for alpha1-antagonist activity, may play an important role in the antihypertensive effect, probably by influencing the pharmacokinetic properties of the antagonist.

Parallel synthesis of a library of bidentate protein tyrosine phosphatase inhibitors based on the alpha-ketoacid motif

Protein tyrosine phosphatases (PTPases) regulate intracellular signal transduction pathways by controlling the level of tyrosine phosphorylation in cells. These enzymes play an important role in a variety of diseases including type II diabetes and infection by the bacterium Yersinia pestis, which is the causative agent of bubonic plague. This report describes the synthesis, using parallel solution-phase methods, of a library of 104 potential inhibitors of PTPases. The library members are based on the bis(aryl alpha-ketocarboxylic acid) motif that incorporates a carboxylic acid on the central benzene linker. This carboxylic acid was coupled with a variety of different aromatic amines through an amide linkage. The aromatic component of the resulting amides is designed to make contacts with residues that surround the active site of the PTPase. The library was screened against the Yersinia PTPase and PTP1B. Based upon the screening results, four members of the library were selected for further study. These four compounds were evaluated against the Yersinia PTPase, PTP1B, TCPTP, CD45, and LAR. Compound 14 has an IC50 value of 590nM against PTP1B and is a reversible competitive inhibitor. This affinity represents a greater than 120-fold increase in potency over compound 2, the parent structure upon which the library was based. A second inhibitor, compound 12, has an IC50 value of 240nM against the Yersinia PTPase. In general, the selectivity of the inhibitors for PTP1B was good compared to LAR, but modest when compared to TCPTP and CD45.

Cascade bio-hydroxylation and dehalogenation for one-pot enantioselective synthesis of optically active beta-halohydrins from halohydrocarbons

A stereoselective hydroxylation and enantioselective dehalogenation cascade reaction was developed for the synthesis of optically active beta-haloalcohols from halohydrocarbons. This cascade system employed P450 and halohydrin dehalogenase as two compatible biocatalysts, allowing a straightforward, greener and efficient access to beta-halohydrins with excellent enantioselectivities (98-99%).

Discovery of substituted 4-(pyrazol-4-yl)-phenylbenzodioxane-2-carboxamides as potent and highly selective Rho kinase (ROCK-II) inhibitors

The identification of a new class of potent and selective ROCK-II inhibitors is presented. Compound 5 (SR-3677) had an IC50 of ?3 nM in enzyme and cell based assays and had an off-target hit rate of 1.4% against 353 kinases, and inhibited only 3 out of 70 nonkinase enzymes and receptors. Pharmacology studies showed that 5 was efficacious in both, increasing ex vivo aqueous humor outflow in porcine eyes and inhibiting myosin light chain phosphorylation.

Rhodium-Catalyzed Oxidative Cycloaddition of N-tert-Butoxycarbonylhydrazones with Alkynes for the Synthesis of Functionalized Pyrroles via C(sp3)?H Bond Functionalization

A rhodium(III)-catalyzed cycloaddition of N-tert-butoxycarbonylhydrazones with internal alkynes was developed. The reaction features a regioselective alpha-imino alkyl C(sp3)?H bond functionalization resulting in selective formation of highly functionalized NH-free pyrroles. Our studies showed that utilizing the N-tert-butoxycarbonyl (N-Boc) as the oxidizing directing group is critical for achieving the observed pyrrole formation versus the isoquinoline formation. To account for the pyrrole formation, we hypothesized that a prior tautomerization of the N-Boc-hydrazones to enamines should occur, followed by regioselective C(sp2)?H cleavage to form a putative five-membered rhodacycle. Subsequent coupling of the rhodacycle with the alkynes would afford the pyrrole products. (Figure presented.).
