  2,3-Dideoxy hex-2-enopyranosid-4-uloses as promising new anti-tubercular agents: Design, synthesis, biological evaluation and SAR studies

  摘要：

  The alarming resurgence of tuberculosis (TB) underlines the urgent need for development of new and potent anti-TB drugs. Towards this goal we herein report the design and synthesis of 2,3-dideoxy hex-2-enopyranosid-4-uloses as promising new anti-tubercular agents. These easily accessible, small molecules were found to exhibit in vitro activity against Mycobacterium tuberculosis H37Rv in a MIC range of 0.78 mu g/mL to 25 mu g/mL. A detailed SAR study on these hex-2-enopyranosid-4-uloses led to the identification of compound 5g (5007-724) which on the basis of low MIC (0.78 mu g/mL-M. tuberculosis H37Rv; 1.56 mu g/mL-MDR, SDR strains of M. tuberculosis; 0.78 mu g/mL-inhibition of intracellular replication of M. tuberculosis) and SI value of 13.5 has been identified as a promising lead molecule.

  C-3 Alkyl/Arylalkyl-2,3-dideoxy Hex-2-enopyranosides as Antitubercular Agents:  Synthesis, Biological Evaluation, and QSAR Study

  摘要：

  A series of C-3 alkyl and arylalkyl 2,3-dideoxy hex-2-enopyranoside derivatives were synthesized by Morita-Baylis-Hillman reaction using enulosides 4,5, and 6 and various aliphatic and aromatic aldehydes. The compounds were evaluated in vitro for the complete inhibition of growth of Mycobacterium tuberculosis H37Rv. They exhibited moderate to good activity in the range of 25-1.56 mu g/mL. Among these, 4d, 4h, 5c, and 4hr showed activity at minimum inhibitory concentrations, 3.12, 6.25, 1.56, and 1.56 mu g/mL, respectively. These compounds were safe against cytotoxicity in VERO cell line and mouse macrophage cell line J 744A.1. A QSAR analysis by CP-MLR with alignment-free 3D-descriptors indicated the relevance of structure space comparable to the minimum energy conformation (from conformational analysis) of 5c to the activity. The study indicates that the compounds attaining the conformational space of 5c and reflecting some symmetry, minimum eccentricity, and closely placed geometric and electronegativity centers therein are favorable for activity.

  The Morita-Baylis-Hillman (MBH) reaction of p-nitrobenzaldehyde with C (6) acyl protected enuloside 1 in the presence of TiCl4/TBAI yielded highly diastereoenriched C-3-branched deoxysugar derivative or MBH adduct 1'a in high yield, while reactions of unprotected enuloside 2a and C (6) alkyl protected enulosides 2d-e with p-nitrobenzaldehyde under the same conditions afforded the adducts 2'a and 2'd-e, respectively, in low yield with moderate selectivity. Several representative aromatic and aliphatic aldehydes were selected to undergo MBH reaction with I to give their respective adducts in very good yield with a very high diastereoselectivity. A plausible mechanism based on the assumption of a Zimmerman-Traxler-type transition state was proposed to explain the excellent selectivity observed with adducts derived from 1. The synthetic application of these adducts were shown by their stereoselective reduction to corresponding threo isomers in very good yield. (C) 2004 Elsevier Ltd. All rights reserved.

  Enulosides, carbohydrate derivatives containing an alpha,beta-unsaturated carbonyl unit, were designed and obtained in high yields and isomeric purity. All synthesized compounds exhibited antitumoral activity in micromolar range against four tested tumor cells lines, being the best results observed for HL-60 cells. These compounds open new possibilities to prepare an array of more active, site-specific or selective antitumor agents. (C) 2017 Elsevier Masson SAS. All rights reserved.
