    which are absent in mammalian cells. The theoretical binding modes of known oxazin-5-ones toward the protein were used as a guide to synthesis new inhibitors. Structural studies of protein-ligand complexes revealed that conformational discrepancies of the derivatives in the protein's binding site gave rise to the variation in their inhibition constant which ranged from 68.58 μM to 2.04 mM.

    Chloro‐substituted phenothiazines and phenoxazines were successfully derivatized with phenylboronic and styrylboronic acids using Suzuki–Miyaura cross‐coupling reaction catalyzed by Pd(0)/XPhos for the first time in good yields. The protocol employed 4 mol% Pd and 7 mol% XPhos with K3PO4 in acetonitrile at 80°C. The reaction condition is compatible with carbonyl and unprotected N–H groups in substrates

    Palladium-catalyzed Suzuki-Miyaura cross-coupling reactions of 6-chloro-5H-benzo[a]phenothiazin-5-one (1), 11-amino-6-chloro-9-thio-5H-naphtho[2,1-b]pyrimido[5,4-e][1,4]oxazin-5-one (2) and 6-chloro-5H-naphtho[2,1-b]pyrido[2,3-e][1,4]oxazin-5-one (3) with phenylboronic acid and 3-nitrophenylboronic acid were thoroughly investigated. The above intermediates were prepared by the reactions of 2-aminothiophenol, 4,5-diamino-6-hydroxylpyrimidine-2-thiol and 2-aminopyridin-3-ol each with 2,3-dichloronaphthalene-1,4-dione in a basic medium using benzene/DMF as the solvent. Thereafter, each was subjected to the Suzuki-Miyaura coupling reaction with phenylboronic acid and 3-nitrophenyl boronic acid, refluxing for 7-8 h at 110 °C using tris(dibenzylideneacetone)palladium(0), dicyclohexyl-phosphino-2,6-dimethoxybiphenyl (SPhos), potassium phosphate and toluene as the catalyst, ligand, base and solvent correspondingly to yield the derivatives (1a-b), (2a-b) and (3a-b), respectively. Structures of the compounds were characterized using UV/visible spectrophotometry, FT-IR, 1H NMR and 13C NMR spectroscopy and elemental analysis. The compounds were screened against six micro-organisms, viz: Bacillus subtitis, Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Candida albicans and Aspergillus niger and were shown to have significant activity against some Gram-positive micro-organisms.
