The cytochrome P450 RauA from Rhodococcus erythropolis JCM 6824 catalyzes the hydroxylation of a nitrogen atom in the quinolone ring of aurachin, thereby conferring strong antibiotic activity on the aurachin alkaloid. Here, we report the crystal structure of RauA in
The unusual role of CO as a signaling molecule in several physiological pathways has spurred research in the area of synthesizing new CO-releasing molecules (CORMs) as exogenous CO donors. Auxiliary control on CO delivery can be achieved if CO can
Potency with potential: 2-Phenoxy-nicotinamides were identified as potent agonists at the GPBAR1 receptor, a target in the treatment of obesity, type 2 diabetes and metabolic syndrome. Extensive structure-activity relationship studies supported by homology modeling and docking resulted in the identification

Zinc sensors based on 2,3-dipicolylamine (DPA) and quinoline have been synthesized. They fluoresced in the presence of Zn(2+) and remained fluorescent when other metal ions were present. Fluorescence enhancement of the sensors was not seen for most other metal ions.

Two new rhodamine based probes 1 and 2 for the detection of Fe(3+) were synthesized and their selectivity towards Fe(3+) ions in the presence of other competitive metal ions tested. The probe 1 formed a coloured complex with Fe(3+) as
