  Synthesis and Antitumor Activity of New Derivatives of Xanthen-9-one-4-acetic Acid

  摘要：

  Xanthen-9-one-4-acetic acid (XAA) analogues in which the substituents in positions 5 and 6 are included in cyclic structures are described. Direct in vitro toxicity of the synthesized compounds against four tumor cell lines was evaluated, and their ability to stimulate mouse peritoneal macrophages and human monocytes in culture to become tumoricidal (indirect toxicity) was also studied. Despite low direct toxicity, almost all,the compounds proved to be able to significantly enhance the lytic properties of both murine macrophages and human monocytes. as well as the parent compound XAA and its most active derivative DMXAA taken as reference. In particular, compounds 4a, 5a, 7a, 13a,b, and 16a,b showed higher activity than the lead compound on human monocytes, compound 7a being 2.5 times more active than DMXAA, which is the most potent compound synthesized so far. Moreover, compounds 4a, 5a, 7a, 13a, 16a, and 16b proved to be able to induce TNF production in human immune cells.

  CNS active cyclic amines derivatives containing heterocyclic xanthone core we designed and synthesized a set of fourteen novel 2- or 4-methylxanthone substituted by alkyl- or aryl-piperazine moieties. The compounds were evaluated in vivo for their potential antidepressant-like activity (in the forced swim test) and anxiolytic-like activity (four-plate test) and their inhibitory effect against rat 5-HT2

  molecules are developed to improve the safety, photostability, solubility, and absorption profile of new derivatives. In our study, we designed and synthesized seventeen novel molecules by combining in the structures two chromophores: xanthone and (E)-cinnamoyl moiety. The ultraviolet spectroscopic properties of the tested compounds were confirmed in chloroform solutions. They acted as UVB or UVA/UVB absorbers

  A series of 17 new aminoalkanol derivatives of 6-methoxy- or 7-chloro-2-methylxanthone as well as 6-methoxy-4-methylxanthone was synthesized and evaluated for anticonvulsant activity. All compounds were verified in mice after intraperitoneal (ip) administration in maximal electroshock (MES) and subcutaneous pentetrazole (scMet) induced seizures as well as neurotoxicity assessment. Eleven of the tested substances showed protection against electrically evoked seizures in the majority of the tested mice at the dose of 100 mg/kg. Additionally, one was effective at the dose of 30 mg/kg. Five substances were active at the dose of 300 mg/kg or at the dose of 100 mg/kg in the minority of the tested mice. The most promising compound revealed ED50 value of 47.57 mg/kg in MES (mice, ip, 1 h after administration) and at the same time its TD50 was evaluated as above 400 mg/kg. Those values gave PI (calculated as TD50/ED50) of more than 8.41. Three other synthesized xanthone derivatives also proved to act as anticonvulsants and showed ED50 values in MES test (mice, ip) ranged 80-110 mg/kg. Results were quite encouraging and suggested that in the group of xanthone derivatives new potential anticonvulsants might be found. (C) 2013 Elsevier Ltd. All rights reserved.
• Potential antitumor agents. 58. Synthesis and structure-activity relationships of substituted xanthenone-4-acetic acids active against the colon 38 tumor in vivo

  In a search for compounds related to flavoneacetic acid with activity against solid tumors, a series of methyl-, methoxy-, chloro-, nitro-, and hydroxy-substituted xanthenone-4-acetic acids have been synthesized and evaluated against subcutaneously implanted colon adenocarcinoma 38 in vivo, using a short-term histology assay as a primary screening system. A major goal of this work was to identify compounds with similar profiles of activity to that of flavoneacetic acid but of higher potency. The level of activity of the compounds appeared to depend more on the nature of the substituent than its positioning, in the order Cl greater than Me, OMe greater than NO2, OH. However, the potency of the compounds was related much more to the position rather than the nature of the substitution, with 5-substituted compounds being clearly the most dose potent. 5-Methylxanthenone-4-acetic acid has a similar level of activity to that of flavoneacetic acid in the test systems employed but is more than 7-fold as dose potent.
