“…(Clusiaceae)], have been investigated extensively for their potential anticancer activity. [24][25][26][27] Several prenylated xanthones have been characterized from our previous work on the stems of Cratoxylum cochinchinense (Lour.) Blume (Hypericaceae), collected in Vietnam, and the stem bark of Garcinia x mangostana, collected in Indonesia, including α-, β-, and γmangostins (10)(11)(12), 8-deoxygartanin (18), gartanin (19), 1,3,7-trihydroxy-2,4diisoprenylxanthone (20), garcinone D (21), 9-hydroxycalabaxanthone (22), 3-isomangostin (23), and 11α-mangostanin (24).…”

“…The anticancer potential of α-mangostin (10) has been discussed in a recent review article. 27 This compound has been found to inhibit matrix metalloproteinase (MMP)-2 and MMP-9 expression in U2OS human osteosarcoma cells and hence to show some potential for the treatment of osteosarcoma. 34 It reduces the expression of both MMP-2 and MMP-9, increases E-cadherin expression, and suppresses the ERK signaling pathways in the MIAPaCa-2 and BxPC-3 pancreatic cancer cell lines to inhibit the invasion, migration, and growth of these cells.…”

“…Thus, this new formulation may represent an improved approach for lung cancer therapy. 81 All cytotoxic benzoxanthones, prenylated xanthones, the normal xanthone, euxanthone (27), and the caged xanthones listed in Tables 1-3 contain an α,β-unsaturated carbonyl group across the C-8, C-8a, and C-9 positions and a hydrogen-bonded hydroxy group at the C-1 position, suggesting that these functional groups are important for mediation of their cytotoxicity. Comparison of the cytotoxicity of these different types of xanthones (Tables 1-3) shows that the cytotoxic potency increases in the sequence benzoxanthones, prenylated xanthones, and caged xanthones.…”

Higher plants are well known for their value in affording clinically useful anticancer agents, with such compounds acting against cancer cells by a range of mechanisms of action. There remains a strong interest in the discovery and development of plant secondary metabolites as additional cancer chemotherapeutic lead compounds. In the present review, progress on the discovery of plant-derived compounds of the biflavonoid, lignan, sesquiterpene, steroid, and xanthone structural types is presented. Several potential anticancer leads of these types have been characterized from tropical plants collected in three countries as part of our ongoing collaborative multi-institutional project. Preliminary structure-activity relationships and work on in vivo testing and cellular mechanisms of action are also discussed. In addition, the relevant work reported by other groups on the same compound classes is included herein.

In this paper, acrylamide is used as a hydrophilic monomer, and octadecyl methacrylate (C18) and polyurethane (PU) monomers are used as hydrophobic monomers. In an aqueous solution containing mixed surfactants of cetyl trimethylammonium bromide and sodium dodecyl sulfate, a series of composite physical hydrogels with dual network structures are synthesized using these three monomers through in situ micelle copolymerization. The results indicate that, with the increase in PU content (<0.08 g), the thermal stability and mechanical properties (stretching and compressive) of the composite gel are enhanced, while the swelling performance becomes poorer. Furthermore, it can heal at room temperature and the self-healing property approaches 88% of that of the original sample after 60 min. Additionally, the self-healing efficiency shows a downward trend with the increase in the amount of PU, which is mainly related to the recovery efficiency of the network chain (polyacrylamide (PAAM) chain and PU chain) and the decrease in the mobility of C18. By constructing the double-crosslinked network, the design and preparation of polymer hydrogels with high stretching capability, good elasticity and self-healing performance provides a new approach to preparing hydrogels with excellent properties.
