In the title compound, C(15)H(11)NO(4)S, the benzothia-zole unit is essentially planar [maximum deviation = 0.0644 (14) Å for the N atom] and forms a dihedral angle 54.43 (6)° with the phenyl ring. In the crystal structure, weak bifurcated C-H⋯O hydrogen bonds involving the carbonyl O atoms as acceptors result in R(2) (2)(7) ring motifs.

A novel tricyclic thiazepine derivative, 6-(p-tolyl)benzo[f] pyrido[2,3-b][1,4] thiazepine 11,11-dioxide (TBPT), exhibits potent inhibitory effects in two non-small-cell lung cancer cell lines, H460 and its drug-resistant variant, H460(TaxR), while exhibiting much less toxic effects on normal human fibroblasts. After five injections of TBPT at a dose of 60 mg/kg, it inhibits H460(TaxR) tumor growth in xenografted mouse models by 66.7% without causing observable toxicity to normal tissues.
