Abstract Five pathways involving different ring structures led to generation of fourteen thienylbenzamides (7–20) which display the structure-activity relationships of class I HDAC inhibitors. All the synthesised compounds inhibit HDAC1 and HDAC2 selectively over other isoforms and many inhibit DLD1 and HCT116 cells more effectively than a parentcompound. Compounds 8 and 16 inhibit HCT116 cells by activation
A series of RuII arene complexes of mono- and bidentate N-donor ligands with carboxyl or ester groups and chlorido ancillary ligands were synthesised and structurally characterised. The complexes have a distorted tetrahedral piano-stool geometry. The binding interaction was studied with calf thymus DNA (CT-DNA) by absorption titration, viscosity measurement, thermal melting, circular dichroism, ethidium

A series of 4-pyridinylaminobenzamides, useful as antihypertensive agents, having the Formula I, IA or IB as defined herein was prepared from the corresponding 4-pyridinylaminobenzoic acids by reacting the acid chloride of the latter with ammonia or a primary or secondary amine. Alternatively the compounds were prepared by reacting an aminobenzamide with 4-chloropyridine or equivalent reagent.

A series of pyrimidine benzamide-based thrombopoietin receptor agonists is described. The lead molecule contains a 2-amino-5-unsubstituted thiazole, a group that has been associated with idiosyncratic toxicity. The potential for metabolic oxidation at C-5 of the thiazole, the likely source of toxic metabolites, was removed by substitution at C-5 or by replacing the thiazole with a thiadiazole. Potency in the series was improved by modifying the substituents on the pyrimidine and/or on the thiazole or thiadiazole pendant aryl ring. In vivo examination revealed that compounds from the series are not highly bioavailable. This is attributed to low solubility and poor permeability. (C) 2007 Elsevier Ltd. All rights reserved.
