Novel benzenesulfonamides as dual VEGFR2/FGFR1 inhibitors targeting breast cancer: Design, synthesis, anticancer activity and in silico studies.

In the current study, a new series of benzenesulfonamides 6a-r was designed and synthesized as dual VEGFR-2 and FGFR1 kinase inhibitors with anti-cancer activity. The 4-trifluoromethyl benzenesulfonamide 6l exhibited the highest dual VEGFR-2/FGFR1 inhibitory activity with IC values of 0.025 and 0.

Novel thiazolidin-4-one benzenesulfonamide hybrids as PPARγ agonists: Design, synthesis and in vivo anti-diabetic evaluation.

In the current study, two series of novel thiazolidin-4-one benzenesulfonamide arylidene hybrids 9a-l and 10a-f were designed, synthesized and tested in vitro for their PPARɣ agonistic activity. The phenethyl thiazolidin-4-one sulphonamide 9l showed the highest PPARɣ activation % by 41.7%.

Novel 2-oxo-2-phenylethoxy and benzyloxy diaryl urea hybrids as VEGFR-2 inhibitors: Design, synthesis, and anticancer evaluation.

Two series of diaryl urea derivatives, 6a-k and 7a-n, were synthesized. All the newly synthesized compounds were tested against the NCI (US) cancer cell lines via SRB assay. The p-chloro-m-trifluoromethyl phenyl derivatives 6e-g and 7e-g showed the most potent cytotoxic activity with a GI value range of 1.

Design, synthesis and anticancer activity of novel 2-arylbenzimidazole/2-thiopyrimidines and 2-thioquinazolin-4(3H)-ones conjugates as targeted RAF and VEGFR-2 kinases inhibitors.

In the current study, series of 2-arylbenzimidazole-thiopyrimidine and -thioquinazolin-4(3H)-ones conjugates 12a-d, 13a,b and 14a-l have been synthesized. All the synthesized compounds were tested in vitro for their anticancer activities against a panel of cancer cell lines at NCI - US and their growth inhibition (GI) % were determined at 10 µM. Compounds 14c and 14g-i were selected to be screened at the five dose assay and were found to exhibit GI values 1.

Design and synthesis of novel quinazolinone-based fibrates as PPARα agonists with antihyperlipidemic activity.

Aiming to discover new antihyperlipidemic agents, a new set of quinazolinone-fibrate hybrids 9a-r bearing the essential features for peroxisome proliferator-activated receptor-α (PPARα) agonistic activity was synthesized and the structures were confirmed by different spectral data. All the target compounds were screened for their PPARα agonistic activity. Compounds 9o and 9q exhibited potent activity, with EC values better than that of fenofibrate by 8.

Novel 2-arylbenzothiazole DNA gyrase inhibitors: Synthesis, antimicrobial evaluation, QSAR and molecular docking studies.

A series of new 2-arylbenzothiazole derivatives (4, 5, 6a-j, 7a-i and 8a,b) was synthesized and tested for their antimicrobial activity against different Gram-positive, Gram-negative bacteria and yeast using ciprofloxacin and fluconazole as positive controls for the antibacterial and antifungal activities, respectively. The target compounds showed stronger inhibitory activity against Gram-negative than Gram-positive bacteria. The minimum inhibitory concentration (MIC) values were determined for those compounds showed zone of inhibition ≥ 13 mm.

Design, synthesis, and molecular docking of novel indole scaffold-based VEGFR-2 inhibitors as targeted anticancer agents.

A series of new indole derivatives 1-18 was synthesized and tested for their cytotoxic activity on a panel of 60 tumor cell lines. Additionally, molecular docking was carried out to study their binding pattern and binding affinity in the VEGFR-2 active site using sorafenib as a reference VEGFR-2 inhibitor. Based on the molecular docking results, compounds 5a, 5b, 6, 7, 14b, 18b, and 18c were selected to be evaluated for their VEGFR-2 inhibitory activity.
