Synthesis of analogues of the 2,3,6-triazaphenothiazine ring system

Treatment of 2,3-dichloroquinoxalines with 2-amino-6-picoline-3-thiol gave a mixture of 2,3-bis(2-amino-6-picolinyl-3-thio)quinoxalines (16, R = H, Cl) and 2,3-bis (N,N-dimethylamino)quinoxalines (15, R = H, Cl) separated by fractional crystallization. A similar reaction of 3-amino-6-methoxypyridine-2(1H)-thione (9) with 4,5-dichloropyridazin-3(2H)-one (21) gave 4-chloro-5-(3-amino-6-methoxypyridyl-2-thio)pyridazin-3(2H)-one (22). Concentrated hydrochloric acid-catalysed cyclization of 22 gave the nonrearranged 7-methoxy-2,3,6-triazaphenothiazin-1(2H)-one. The action of compound 22 in refluxing glacial acetic acid gave, on the other hand, 7-methoxy-2,3,6-triazaphenothiazin-4(3H)-one via a Smiles rearrangement. These cyclized compounds are the first known derivatives of the new 2,3,6-triazaphenothiazine ring system.

Rational design and binding of modified cell-wall peptides to vancomycin-group antibiotics: Factorising free energy contributions to binding

Modified cell-wall peptides have been rationally designed and studied in a semi-quantitative approach to factorising free energy contributions in binding to vancomycin-group antibiotics in aqueous solution. Binding energies for succinyl and fumaryl-D-Ala dipeptides. and N-oxalyl-gamma-aminobutyric acid analogues, are compared with binding energies for the natural substrate N-Ac-D-Ala-D-Ala, and the truncated mono-peptide N-Ac-D-Ala. We estimate the binding energy of the N-terminal carboxyl group, by four independent analyses, to he -(14 to 17)¡À7 kJ mol-1 when differences in ligand binding energies are corrected for differences in contributions from the “cost” of restricting rotations and “benefits” of hydrophobic interactions. The carboxylate interaction comprises both a charged – COO-…HN hydrogen bond plus face to face pi-stacking between the carboxylate group and an aromatic ring in the antibiotic binding pocket.

Coordination Assisted Distal C?H Alkylation of Fused Heterocycles

Distal C?H bond functionalization of heterocycles remained extremely challenging with covalently attached directing groups (DG). Lack of proper site for DG attachment and inherent catalyst poisoning by heterocycles demand alternate routes for site selective functionalization of their distal C?H bonds. Utilizing non-productive coordinating property to hold the heterocycle into the cavity of a template system in a host?guest manner, we report distal C?H alkylation (C-5 of quinoline and thiazole, C-7 of benzothiazole and benzoxazole) of heterocycles. Upon complexation with heterocyclic substrate, nitrile DG in template directs the metal catalyst towards close vicinity of the specific distal C?H bond of the heterocycles. Our hypothesized pathway has been supported by various X-ray crystallographically characterized intermediates.
