Herein, further SAR studies of lead compound NSC746457 (Shen, J.; Woodward, R.; Kedenburg, J. P.; Liu, X. W.; Chen, M.; Fang, L. Y.; Sun; D. X.; Wang. P. G.J. Med. Chem. 2008, 51, 7417-7427) were performed, including the replacement of the trans-styryl moiety with a 2-substituted benzo-hetero aromatic ring and the introduction of a substituent onto the central methylene carbon. A promising chiral lead, S-(E)-3-(1-(1-(benzo[d]oxazol-2-yl)-2-methylpropyl)-1H-1,2,3- triazol-4-yl)-N-hydroxyacrylamide (12, NK-HDAC-1), was discovered and showed about 1 order of magnitude more potency than SAHA in both enzymatic and cellular assays. For the in vitro safety tests, NK-HDAC-1 was far less toxic to nontransformed cells than tumor cells and showed no significant inhibition activity against CYP-3A4. The pharmaceutical properties (LogD, solubility, liver micrsomal stability (t1/2), plasma stability (t1/2), and apparent permeability) strongly suggested that NK-HDAC-1 might be superior to SAHA in bioavailability and in vivo half-life.
Stereoselective chemoenzymatic synthesis of enantiopure 1-(Heteroaryl)ethanamines by lipase-Catalysed kinetic resolutions

The efficient chemical synthesis and enzymatic kinetic resolution of a family of 1-(heteroaryl)ethanamines have been performed with lipases responsible for the preparation of nitrogenated compounds in high optical purity. Thus, Candida antarctica lipase type B has been identified as an excellent biocatalyst for the stereoselective production of the corresponding enantiomerically enriched (B)-acetamides and (S)-amines. A similar effect of the heteroatom in the cyclic ring has been observed in terms of reactivity and enantio- selectivity, with benzoxazole, benzothiazole and benzimidazole derivatives being obtained with excellent enantiopurities after one day of reaction.
