Synthesis of Antifungal Evaluation of 2H-[1,2,3]Triazolo[4,5-g]isoquinoline-4,9-diones

2H-[1,2,3]Triazolo[4,5-g]isoquinoline-4,9-diones and 2H-[1,2,3]triazolo[4,5-g]quinoline-4,9-diones were synthesized and tested for in vitro antifungal activity against pathogenic fungi. Many of those synthesized showed potent antifungal activity. Compounds 3a, 3b, 3g, and 3h completely inhibited the growth of all fungal species tested at the MIC level of 0.8-12.5 mu g/mL. The results suggest that 2H-[1,2,3]triazolo[4,5-g]-isoquinoline-4,9-diones could be antifungal agents.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 27655-40-9, in my other articles.

Effects of newly synthetized isoquinoline derivatives on rat uterine contractility and ROCK II activity

Protein kinases have an important role in signal transduction in the cellular system via protein phosphorylation. RhoA activated Rho-kinases have a pivotal role in the regulation of smooth muscle contraction. ROCK I and ROCK II phosphorylate myosin-phosphatase and myosin-kinase, which induces contraction in the myometrium. Several studies have investigated the affinity of isoquinoline alkaloids (HA-1077, H1152P) to Rho-kinases, and these compounds notably inhibited the Ca2+ -independent process. We measured the efficiency of 25 original, newly synthesized isoquinoline derivatives for the Rho-kinase activity using Rho-associated kinase activity assay and determined their effects on the non-pregnant, 20-day pregnant and parturient rat myometrial contraction in vitro. The IC50 values of 11 from among the 25 derivatives were significantly lower on the oxytocin-induced non-pregnant rat uterine contraction compared with Y-27632 and fasudil, although their maximal inhibitory effects were weaker than those of Y-27632 and fasudil. We measured the effects of 11 isoquinoline molecules with significant IC50 values on ROCK II activity. We found two isoquinolines out of 11 compounds (218 and 852) which decreased the active ROCK II level similarly as Y-27632. Then we found that 218 and 852 relaxed the 20th-day pregnant and parturient rat uterus with greater potency as compared with fasudil. The majority of the synthesized isoquinoline derivatives have uterus relaxant effects and two of them significantly suppress the Rho-kinase mediated myosin light chain phosphorylation. Our results may suggest that the isoquinoline structure has a promising prospect for the development of new and effective inhibitors of uterine contractions in preterm birth. (C) 2017 Elsevier Ltd.

Carbonylation of ethanol using Ni-isoquinoline complex catalyst: Activity and selectivity studies

The carbonylation of ethanol using NiCl2 . 6H(2)O/isoquinoline catalyst system and aqueous HI as a promoter has been investigated. Effect of catalyst, ethanol and HI concentration, temperature, partial pressures of CO and H-2, N- or P-containing ligands and co-catalysts on the activity and selectivity has been studied. The Ni catalysts were found to be active only in;he presence of N- or P-containing ligands. LII and NaI were found to further enhance the catalytic activity without affecting the selectivity. Activity of Ni-isoquinoline-HI catalyst was found to be constant even after 4 recycles indicating high stability.
