  The resurgence Of tuberculosis (TB), the incidence of drug-resistant strains of Mycobacterium tuberculosis (MTB), and the coinfection between TB and HIV have led to serious infections, high mortality, and it global health threat, resulting in the urgent search for new classes of antimycobacterial agents. Herein, we report the identification of a novel class of tetrahydroindazole based compounds as potent and unique inhibitors of MTB. Compounds 6a, 6m, and 6q exhibited activity in the low micromolar range against replicating Mycobacterium tuberculosis (R-TB) phenotype, with minimum inhibitory concentrations (MICs) of 1.7, 1.9, and 1.9 mu M, respectively, while showing no toxicity to Vero Ccells, Moreover, studies aimed to assess the in vitro metabolic stability of 6a and 6m in mouse liver microsomes and in vivo pharmacokinetic profiles in plasma levels gave satisfactory results. This research suggests that tetrahydroindazole based anti-TB compounds can serve its a promising lead scaffold in developing new drugs to combat tuberculosis infections.

  A new series of pyrazolo[3,4-h]quinolines, heteroanalogues of angelicin was conveniently prepared with a broad substitution pattern. A large number of derivatives was obtained and the cellular photocytotoxicity was evaluated in vitro against 5 different human tumor cell lines with GI(50) values reaching the nanomolar level (14.52-0.04 mu M). Selected compounds were able to photoinduce a massive cell death with the involvement of mitochondria. Their photodamage cellular targets were proteins and lipids and they did not cause any kind of DNA photodamage. This latter event is of considerable importance in the modulation of long term side effects, generally associated with the use of classical furocoumarins. (C) 2015 Elsevier Masson SAS.
