Microtubule inhibitors containing immunostimulatory agents promote cancer immunochemotherapy by inhibiting tubulin polymerization and tryptophan-2,3-dioxygenase
摘要:
A combination therapeutic regimen via introducing tryptophan 2,3-dioxygenase inhibitors into microtubule inhibitors was performed and evaluated for their antitumor activity. Thereinto, HT2, composed of combretastatin A-4 (CA-4) and tryptophan-2,3-dioxygenase (TDO) inhibitor by a linker, displayed the most potent activity with 10-fold higher than its parent CA-4 against HepG2, A549 and HCT-116 cancer cell lines. Mechanism studies suggested that HT2 inhibited tubulin polymerization and cell migration, caused G2 phase arrest, induced apoptosis by mitochondrial mediated apoptotic pathway, concurrent depolarized the mitochondria membrane potentials and caused reactive oxygen species (ROS) production in HepG2 cells. Moreover, HT2 could enhance T-cell immune responses in vitro by releasing a TDO inhibitor to suppress TDO expression and blockade kynurenine production. As expected, HT2 could remarkably promote the antitumor activity of CA-4 in either immunocompetent H22 or immunodeficient A549 tumor xenograft models without observable toxic effects. More importantly, HT2 increased the level of splenic and tumor-infiltrated T cells and in turn effectively boosted the inhibition effect in H22 xenografted tumor growth. Collectively, this immunochemotherapeutic strategy can be applied to promote chemotherapeutic effect. (C) 2019 Elsevier Masson SAS. All rights reserved.

Efficient Synthesis of C3‐Alkylated and Alkenylated Indoles via Manganese‐Catalyzed Dehydrogenation
Indoles are a popular heterocycle scaffold that can be found in various natural products and advanced materials, which are related to our daily life commodities. In this work, we developed an efficient method to synthesize C3-alkylated and alkenylated indoles via manganese-catalyzed dehydrogenative transformation of benzyl alcohols and 2-arylethanols with indoles under mild conditions with high yield

Steviol and isosteviol were prepared from the commercially available sweetener stevioside and converted into lipophilic F16 hybrids. Their cytotoxicity was determined in SRB assays and showed to depend on both the substitution pattern of the aromatic substituent as well as on the spacer length. Therefore, compound 25 held an IC50 (A2780) of 180 nM, thus surpassing the activity of comparable rhodamine
