AbstractMyristoylation, the N-terminal addition of the fatty acid myristate to proteins, regulates membrane-bound signal transduction pathways important in cancer cell biology. This modification is catalyzed by two N-myristoyltransferases, NMT1 and NMT2. Zelenirstat is a first-in-class potent oral small molecule inhibitor of both NMT1 and NMT2 proteins. Patients with advanced solid tumors and relapsed/refractory (R/R) B-cell lymphomas were enrolled in an open label, phase I dose escalation trial of oral daily zelenirstat, administered in 28-day cycles until progression or unacceptable toxicity. The endpoints were to evaluate dose-limiting toxicities (DLT) to establish a maximum tolerated dose (MTD), pharmacokinetic parameters, and anticancer activity. Twenty-nine patients were enrolled (25 advanced solid tumor; 4 R/R B-cell lymphoma) and 24 were DLT-evaluable. Dosing ranged from 20 mg once daily (OD) to 210 mg OD without DLT, but gastrointestinal DLTS were seen in the 280 mg cohort. MTD and recommended phase 2 dose were 210 mg OD. Common adverse events were predominantly Gr ≤ 2 nausea, vomiting, diarrhea, and fatigue. Plasma concentrations peaked at 2 h with terminal half-lives averaging 10 h. Steady state was achieved by day 15, and higher doses achieved trough concentrations predicted to be therapeutic. Stable disease as best response was seen in eight (28%) patients. Progression-free survival and overall survival were significantly better in patients receiving 210 mg OD compared to those receiving lower doses. Zelenirstat is well-tolerated, achieves plasma exposures expected for efficacy, and shows early signs of anticancer activity. Further clinical development of zelenirstat is warranted.

AbstractPyrazolic hybrids appended with naphthalene, p‐chlorobenzene, o‐phenol and toluene have been synthesized using Claisen Schmidt condensation reaction of 1‐benzyl‐3,5‐dimethyl‐1H‐pyrazole‐4‐carbaldehyde. All compounds were characterized by various spectroscopic techniques. Compound (E)‐3‐(1‐benzyl‐3,5‐dimethyl‐1H‐pyrazol‐4‐yl)‐1‐(4‐chlorophenyl)prop‐2‐en‐1‐one crystallizes in monoclinic crystal system with C2/c space group. These synthesized compounds were tested for cytotoxic activity and among these compounds 4b and 5a shows prominent cytotoxic activity against triple‐negative breast cancer (TNBC) cells MDA‐MB‐231 with IC50 values 47.72 μM and 24.25 μM, respectively. Distinguishing morphological changes were noticed in MDA‐MB‐231 cells treated with pyrazole hybrids contributing to apoptosis action. To get more insight into cytotoxic activity, in silico molecular docking of these compounds were performed and the results suggested that (E)‐3‐(1‐benzyl‐3,5‐dimethyl‐1H‐pyrazol‐4‐yl)‐1‐(p‐tolyl)prop‐2‐en‐1‐one and 1‐(1′‐benzyl‐5‐(4‐chlorophenyl)‐3′,5′‐dimethyl‐3,4‐dihydro‐1′H,2H‐[3,4′‐bipyrazol]‐2‐yl)ethan‐1‐one binds to the prominent domain of Akt2 indicating their potential ability as Akt2 inhibitor. Moreover, from in silico ADME studies clearly demonstrated that these compounds may be regarded as a drug candidate for sub‐lingual absorption based on log p values (2.157–4.924). These compounds also show promising antitubercular activity. The overall results suggest that pyrazolic hybrids with substitution at less sterically hindered positions have appealing potent cytotoxic activity and antituberculosis activity due to which they may act as multidrug candidate.

Synthesis, biological screening and in silico studies of new N-phenyl-4-(1,3-diaryl-1H-pyrazol-4-yl)thiazol-2-amine derivatives as potential antifungal and antitubercular agents

Article

作者: Chavan, Abhijit ; Pissurlenkar, Raghuvir R S ; Maliwal, Deepika ; Nandurkar, Yogesh ; Katade, Sushma ; Mhaske, Pravin C ; Bhoye, Manish R

A new series of N-aryl-4-(1,3-diaryl-1H-pyrazol-4-yl)thiazol-2-amine, (8a-x) have been synthesized by a cyclo-condensation reaction of 2-bromo-1-(1,3-diphenyl-1H-pyrazol-4-yl)ethanone (6a-f) with N-aryl thiourea, (7a-d). The structure of newly synthesized N-aryl-4-(1,3-diaryl-1H-pyrazol-4-yl)thiazol-2-amine, (8a-x) derivatives was analyzed by ¹H NMR, ¹³C NMR and Mass spectral analysis. The compounds 8a-x were screened for in vitro antimicrobial activity against Escherichia coli, Proteus mirabilis, Bacillus subtilis, Staphylococcus aureus, Candida albicans and Aspergillus niger. and antitubercular activity against M. tuberculosis H37Rv strain. Among the twenty-four pyrazolyl-thiazole derivatives, six compounds 8a, 8b, 8j, 8n, 8o and 8s showed good activity against S. aureus. Against A. niger, all synthesized derivatives showed good antifungal activity. Fifteen pyrazolyl-thiazole derivatives 8a, 8f, 8g, 8h, 8j, 8k, 8n, 8o, 8p, 8q, 8r, 8s, 8t, 8w and 8x showed good antitubercular activity with MIC 1.80-7.34 μM (0.8-3.12 μg/mL), these derivatives have showed more activity than the drugs isoniazid and ethambutol. The active compounds were further screened for cytotoxicity activity against the mouse embryonic fibroblast cells (3t3l1) cell lines at 12.5 and 25 μg/mL concentrations and found less or non-cytotoxicity. To know the plausible mode of action, the synthesized pyrazolyl-thiazole derivatives were studied for pharmacokinetics, toxicity profiles and binding interactions along with an in-depth analysis of structural dynamics and integrity using prolonged molecular dynamics (MD) simulation. The compounds have shown significant docking scores in the range of -7.98 to -5.52 and -9.44 to -7.2 kcal/mol with the M. tuberculosis enoyl reductase (M. tb. InhA) and C. albicans sterol 14-α demethylase (C. ab. CYP51), respectively. Thus, the significant antifungal and antitubercular activity of N-aryl-4-(1,3-diaryl-1H-pyrazol-4-yl)thiazol-2-amine, (8a-x) derivatives incited that, these scaffolds could assist in the development of lead compounds to treat fungal and antitubercular infections.
