Despite their uncertain identification, σ2 receptors are promising targets for the development of diagnostics and therapeutics for tumor diseases. Among the σ2 ligands developed, the class of the flexible benzamides furnished an opti

DOXP-reductoisomerase (DXR) is a validated target for the development of antimalarial drugs to address the increase in resistant strains of Plasmodium falciparum. Series of aryl- and heteroarylcarbamoylphosphonic acids, their diethyl esters and disodium salts have been prepared as analogues of the potent DXR inhibitor fosmidomycin. The effects of the carboxamide N-substituents and the length of the methylene linker have been explored using in silico docking studies, saturation transfer difference NMR spectroscopy and enzyme inhibition assays using both EcDXR and PfDXR. These studies indicate an optimal linker length of two methylene units and have confirmed the importance of an additional binding pocket in the PfDXR active site. Insights into the constraints of the PfDXR binding site provide additional scope for the rational design of DXR inhibitors with increased ligand-receptor interactions.
Synthesis of novel 3,4-dihydroquinolin-2(1H)-one guanidines as potential antihypertensive agents

Hydroxy-3,4-dihydroquinolin-2(1H)-ones (4a-c) were synthesized by intramolecular Friedel Craft alkylation of N-(methoxyphenyl)-3- chloropropionamides (3a-c), obtained by acylation of anisidine with chloropropionyl chloride. The hydroxy-3,4-dihydro quinolin-2(1H)- ones (4a-c) were treated with various dibromo alkanes under phase transfer catalyst conditions at room temperature to give bromoalkyloxy- 3,4-dihydroquinolin-2(1H)- ones (5a-l) which on further reaction with guanidine hydrochloride in dimethyl formamide afforded N-{4- [(2-oxo-1,2,3,4-tetrahydroquinolin-5-yl)oxy]alkyl} guanidines (6a-l). These compounds were synthesized as potential antihypertensive agents.
