Four novel TPDCA derivatives were prepared via a supersaturation method combining TPDCA with water, N-methyl-2-pyrrolidone (NMP), Na(PO2H2), and ammonia solution: 2(C9H7NO5S)H2O (1), (C9H7NO5S)C5H9NO (2), (C9H7NO5S)Na(PO2H2) (3), and (C9H5NO5S)(NH4)2(H2O) (4). Their crystal structures were determined by single-crystal X-ray diffraction. Compounds (1) and (2) crystallize in the monoclinic space groups P21 and P21/c, respectively, whereas compounds (3) and (4) crystallize in the triclinic space group P1-. Weak and moderate hydrogen bonds were detected in the four compounds. In the biological tests, (1) and (3) exhibited significant antibacterial activity against Escherichia coli and Staphylococcus aureus; in addition, (1) was cytotoxic against leukemia HL-60 cells with the IC50 value of 158.5 ± 12.5 μM.
