Novel pyrazine derivatives have the formula (1) in which:
wherein R is a hydrogen atom or a lower alkyl group;
Rl is a lower alkoxy group, a lower alkyl group or a hydroxy group;
R³ is a lower alkyl group, a phenyl group, a phenyl- lower alkyl group, a lower alkenyl group or an indolyl-lower alkyl group;
R² is a phenyl-lower alkyl group which may have, on the phenyl ring, l to 3 substituents selected from the group consisting of a lower alkoxy group, a phenyl-lower alkoxy group, a lower alkyl group and a hydroxy group; a group of the formula
wherein R⁴ and R ⁵ have the meanings given in the description. Processes for preparing the pyrazine derivatives are also described. These compounds can be used in pharmaceutical compositions for inhibiting the activities of superoxide radical (O₂⁻) and for preventing and treating nephritis.

Indole-3-amides and dipeptides were produced from 2-aminobenzothiazoles using the PyBop peptide coupling reagent. These analogues were tested in anti-cancer cell viability assays against SH-SY5Y neuroblastoma and MDA-MB-231 breast adenocarcinoma cell lines, and were found to exhibit cytotoxic activities at concentrations ranging from 0.1 to 20 mu M. These compounds were also found to act additively with a low dosage of 13-cis-retinoic acid in neuroblastoma cells. Then, using neuroblastoma cells transfected to stably overexpress the RAR beta(2) gene, a SAR was developed for the indole-3-amides. Real-time PCR was also used to demonstrate their RAR beta(2) agonistic activity. (C) 2012 Elsevier Ltd. All rights reserved.
