Adenosine analogs as inhibitors of tyrosyl-tRNA synthetase: Design, synthesis and antibacterial evaluation
摘要:
Herein we describe the synthesis and evaluation of a series of adenosine analogs for in vitro antibacterial activity against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. Out of these compounds, compound c6 has much stronger antibacterial potency against Pseudomonas aeruginosa than ciprofloxacin, and was determined to target tyrosyl-tRNA synthetase with IC50 zof 0.8 +/- 0.07 mu M. Structure-activity relationship analysis suggested that introduction of a fluorine atom at the 3'-position of benzene ring of the phenylacetyl moiety significantly increased affinities to the enzyme. In comparison with isopropylidene analogs, 2',3'-deprotected compounds displayed higher inhibitory activity. Molecular dockings provided an explanation for observations in biological assays.

Lipase-mediated acylation of nucleosides with oxime esters in organic solvents has been achieved. Candida antarctica lipases (SP435 and SP435A) showed high regioselectivity toward the primary hydroxyl group of both deoxy- and ribonucleosides, whereas other lipases exhibited poor results for this goal. 2'-Deoxynucleosides, such as thymidine and 2'-deoxyadenosine, were acylated with oxime esters carrying saturated, unsaturated, aromatic, and functionalized chains, giving 5'-O-acylated compounds together with small quantities of the 3'-O-acylated regioisomer. Uridine, adenosine, and inosine, as representative ribonucleosides, were acylated exclusively at the 5'-OH by using the same methodology. Nucleosides bearing a cytosine ring were found to be unreactive with oxime esters under the same conditions. 2'-Deoxycytidine was acylated with acid anhydrides and C. antarctica lipase to give N,5'-O-diacylated compounds, whereas cytidine gave mixtures, reason for which it had to be previously chemically N-acylated and then subjected to the oxime esters and lipase, giving the same results as ribonucleosides.

The invention thus relates to the use, as agent for the treatment of human perspiration in a cosmetic composition, of adenosine and/or one of its derivatives of formula (I). The invention also relates to a cosmetic method for treating human perspiration and optionally human body odours, which consists in applying, to the surface of the skin, a composition comprising, in a cosmetically acceptable medium, at least adenosine and/or one of its derivatives of formula (I) and also its salts, optical isomers and solvates as defined in any one of Claims 1 to 7.
