5-Fluorouracil (5-FU) was linked with F16 by vulnerable bonds to selectively target cancer mitochondria which resulted in conjugated compounds, including F16–5-FU, F16–OOC-FU, F16–NHOC-FU and F16–SS-FU. F16–OOC-FU decreased the antiproliferative activity of 5-FU on the nontumor cell line, and the cytotoxicity of F16–SS-FU significantly increased when administered with dithiothreitol (DTT).

targeting mitochondria and the fluorophore tracing ability, a fluorescent mitochondria-targeted organic arsenical PDT-PAO-F16 was fabricated, which not only visualized the cellular distribution, but also exerted anti-cancer activity in vitro and in vivo via targeting pyruvate dehydrogenase complex (PDHC) and respiratory chain complexes in mitochondria. In details, PDT-PAO-F16 mainly accumulated into

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

Tryptophan catabolism mediated by indoleamine 2,3-dioxygenase (IDO) is an important mechanism of peripheral immune tolerance contributing to tumoral immune resistance. IDO inhibition is thus an active area of research in drug development. Recently, our group has shown that tryptophan 2,3-dioxygenase (TDO), an unrelated hepatic enzyme also catalyzing the first step of tryptophan degradation, is also expressed in many tumors and that this expression prevents tumor rejection by locally depleting tryptophan. Herein, we report a structure- activity study on a series of 3-(2-(pyridyl)ethenyl)indoles. More than 70 novel derivatives were synthesized, and their TDO inhibitory potency was evaluated. The rationalization of the structure-activity relationships (SARs) revealed essential features to attain high TDO inhibition and notably a dense H-bond network mainly involving His(55) and Thr(254) residues. Our study led to the identification of a very promising compound (58) displaying good TDO inhibition (K-i = 5.5 mu M), high selectivity, and good oral bioavailability. Indeed, 58 was chosen for preclinical evaluation.
Novel tryptophan dioxygenase inhibitors and combined tryptophan dioxygenase/5-HT reuptake inhibitors
Tryptophan dioxygenase (TDO) is a liver enzyme that is responsible for the majority of the metabolism of tryptophan. A series of novel 3-(2-pyridylethenyl)indoles are shown to be potent inhibitors of TDO with selected members of the series also having 5-hydroxy tryptamine (5-HT) reuptake inhibitory activity. These compounds are shown to provide significant increases in the levels of tryptophan and 5-HT in the cerebrospinal fluid and are thus of interest for antidepressant therapy.
