Cytotoxic benzophenone and triterpene from Garcinia hombroniana.
Garcinia hombroniana (seashore mangosteen) in Malaysia is used to treat itching and as a protective medicine after child birth. This study was aimed to investigate the bioactive chemical constituents of the bark of G. hombroniana. Ethyl acetate and dichloromethane extracts of G. hombroniana yielded two new (1, 9) and thirteen known compounds which were characterized by the spectral techniques of NMR, UV, IR and EI/ESI-MS, and identified as; 2,3',4,5'-tetrahydroxy-6-methoxybenzophenone(1), 2,3',4,4'-tetrahydroxy-6-methoxybenzophenone (2), 2,3',4,6-tetrahydroxybenzophenone (3), 1,3,6,7-tetrahydroxyxanthone (4), 3,3',4',5,7-pentahydroxyflavone (5),3,3',5,5',7-pentahydroxyflavanone (6), 3,3',4',5,5',7-hexahydroxyflavone (7), 4',5,7-trihydroxyflavanone-7-rutinoside (8), 18(13→17)-abeo-3β-acetoxy-9α,13β-lanost-24E-en-26-oic acid (9), garcihombronane B (10), garcihombronane D (11), friedelan-3-one (12), lupeol (13), stigmasterol (14) and stigmasterol glucoside (15). In the in vitro cytotoxicity against MCF-7, DBTRG, U2OS and PC-3 cell lines, compounds 1 and 9 displayed good cytotoxic effects against DBTRG cancer cell lines. Compounds 1-8 were also found to possess significant antioxidant activities. Owing to these properties, this study can be further extended to explore more significant bioactive components of this plant.

Synthesis, xanthine oxidase inhibition, and antioxidant screening of benzophenone tagged thiazolidinone analogs.
A series of novel 2-(diaryl methanone)-N-(4-oxo-2-phenyl-thiazolidin-3-yl)-acetamides were synthesized by various Schiff bases of (4-benzoyl-phenoxy)-aceto hydrazide with thioglycolic acid. The structures of the newly synthesized compounds were confirmed by IR, (1) H NMR, mass spectra, and C, H, N analysis. Further, all the synthesized compounds 9a-n were evaluated for xanthine oxidase (XO) inhibition and antioxidant properties. Among all the tested compounds, 9f, 9m, and 9n demonstrated potent XO inhibition of 52, 76, and 26%, respectively, compared to the standard drug allopurinol, which is evident from in vitro and in silico analysis. On the other hand, compounds 9c, 9d, and 9k exhibit potent antioxidant properties.
