• Design, Synthesis and Antitubercular Activity of Certain Nicotinic Acid Hydrazides

  日期：——

  Three series of 6-aryl-2-methylnicotinohydrazides 4a–i, N′-arylidene-6-(4-bromophenyl)-2-methylnicotino hydrazides 7a–f, and N′-(un/substituted 2-oxoindolin-3-ylidene)-6-(4-fluorophenyl)-2-methylnicotinohydrazides 8a–c were synthesized and evaluated for their potential in vitro antimycobacterial activity against M. tuberculosis. The results showed that isatin hydrazides 8a–c are remarkably more active than the parent hydrazide 4c. Hydrazides 8b and 8c exhibited the highest activity among all the tested compounds (MIC = 12.5 and 6.25 µg/mL, respectively). Compounds 8b and 8c were also devoid of apparent cytotoxicity to HT-29, PC-3, A549, HepG2 and MCF-7 cancer cell lines. Besides, 8b and 8c showed good drug-likeness scores of 0.62 and 0.41, respectively. Those two isatin hydrazides could offer an excellent framework for future development to obtain more potent antitubercular agents. The SAR study suggested that lipophilicity of the synthesized derivatives is a crucial element that accounts for their antimycobacterial activity. Finally, a theoretical kinetic study was established to predict the ADME of the active derivatives.

• Protective effect of novel substituted nicotine hydrazide analogues against hypoxic brain injury in neonatal rats via inhibition of caspase

  In hypoxic-ischemic injury of the brain of neonates, the level of caspase-3 was found to be aberrantly activated. Its overexpression leads to the alteration of cytoskeleton protein fodrin and loss of DNA repair enzyme which ultimately results in neurological impairment and disability. Concerning this, the present study was intended to develop novel nicotine hydrazide analogues as caspase inhibitors via efficient synthetic route. These compounds were subsequently tested for inhibitory activity against caspase-3 and -7 where they exhibit highly potent activity against caspase-3 revealing compound 5k as most potent inhibitor (IC50 = 19.4 +/- 2.5 mu M). In Western blot analysis, 5k considerably inhibits the overexpression of caspase-3. The aryl nicotinate of compound 5k, as indicated by molecular docking was found to engage His121 and critical enzyme thiols, i.e., Cys163 of caspase-3 for its potent activity. Moreover, histopathological examination of brain tissues and hippocampus neurons showed that compound 5k considerably improves the brain injury and exert neuroprotective effects in hypoxic-ischemic (HI). In brain homogenate, 5k significantly improves the activity of MDA, SOD, GSH-Px, CAT and T-AOC to exert its beneficial effect against oxidative stress induced by HI injury. (C) 2016 Elsevier Ltd.

• Design, synthesis and QSAR study of certain isatin-pyridine hybrids as potential anti-proliferative agents

  A hybrid pharmacophore approach was adopted to design and synthesize new series of isatin-pyridine hybrids. All the newly prepared hybrids (5a-o, 8 and 11a-d) were in vitro evaluated for their antiproliferative activity against three human cancer cell lines, namely HepG2 hepatocellular carcinoma, A549 lung cancer and MCF-7 breast cancer. Compound 8 emerged as the most active member against HepG2 cell line (IC50 = 2.5 +/- 0.39 mu M), with 2.7-fold increased activity than the reference drug, doxorubicin (IC50 = 6.9 +/- 2.05 mu M). Whilst, compound 11c was found to be the most potent counterpart against A549 and MCF-7 cell lines with IC50 values of 10.8 +/- 1.15 and 6.3 +/- 0.79, respectively. The weightiness of the utilization of non-cleavable linker, as the chalcone linker, and simplification of the first group, was explored via the SAR study. Furthermore, a QSAR model was built to explore the structural requirements controlling the cytotoxic activities. Notably, the predicted activities by the QSAR model were very close to those experimentally observed, hinting that this model could be safely applied for prediction of more efficacious hits comprising the same skeletal framework. Finally, a theoretical kinetic study was established to predict the ADME of the active hybrids. (C) 2014 Elsevier Masson SAS. All rights reserved.
• Novel 1,3,5‐triazine‐nicotinohydrazide derivatives induce cell arrest and apoptosis in osteosarcoma cancer cells and inhibit osteosarcoma in a patient‐derived orthotopic xenograft mouse model

  AbstractThe present study deals with developing novel 1,3,5‐triazine‐nicotinohydrazide derivatives as potent CDK9 inhibitors in a straightforward synthetic route with potent anti‐osteosarcoma activity. The most potent CDK9 inhibitor compound 5k inhibits proliferation of MG‐63 cells via induction of apoptosis and G2/M cell cycle arrest. It reduces tumor progression in the patient‐derived orthotopic xenograft (PDOX) mouse model with significant antioxidant and anti‐inflammatory activity. In tumor tissue homogenates, it caused significant inhibition of CDK9 and inhibited the phosphorylation of RNAPII ser2 and reduced MCL‐1 expression in Western blot analysis. Compound 5k also showed considerable bioavailability in SD mice. Our results demonstrated that compound 5k inhibits growth of OS in vitro and in vivo via inhibition of CDK9 which attenuated the downstream phosphorylation of RNAPII ser2 and represses expression of the anti‐apoptotic protein, MCL‐1 for the induction of apoptosis in OS.

  Herein we introduce new compounds as conjugates of arylnicotinic acids with aryl (thio)semicarbazide derivatives. Based on a structure-guided approach, they were designed to possess anti-leishmanial activity through anti-folate mechanism, via targeting Leishmania major pteridine reductase 1 (Lm-PTR1). The in vitro anti-promastigote and anti-amastigote activity were promising for many thiosemicarbazide
