Phenolic Schiff bases are known for their diverse biological activities and ability to scavenge free radicals. To elucidate (1) the structure-antioxidant activity relationship of a series of thirty synthetic derivatives of 2-methoxybezohydrazide phenolic Schiff bases and (2) to determine the major mechanism involved in free radical scavenging, we used(More)
Using structure-based virtual screening approach, a coumarin derivative (1) was identified as β-glucuronidase inhibitor. A focused library of coumarin derivatives was synthesized by eco-benign version of chemical reaction, and all synthetic compounds were characterized by using spectroscopy. These compounds were found to be inhibitor of β-glucuronidase with(More)
2,4-Dimethylbenzoylhydrazones 1-30 were synthesized by condensation reactions of 2,4-dimethylbenzoylhydrazide with various aromatic aldehydes and characterized. The assigned structures of compounds 10, 15 and 22 were further supported by single-crystal X-ray diffraction data. The synthesized compounds were evaluated for their in vitro DPPH radical(More)
This paper presents a novel agent-based design for Arabic speech recognition. We define the Arabic speech recognition as a Multi-Agent-System where each agent has a specific goal and deals with that goal only. Once all the small tasks are accomplished the big task is too. A number of agents are required in order to recast Arabic speech recognition, namely(More)
Based on the previous reports on α-glucosidase inhibitory activity of benzimidazole class, we intend to evaluate further this class as potential inhibitors of α-glucosidase enzyme. Thus, in the current study synthesis of 5-bromo-2-aryl benzimidazole derivatives 1–25 was carried out. All the synthetic compounds were characterized by different spectroscopic(More)
In the search of potent antidiabetic drug, we synthesized 1–25 2-(2-methoxyphenyl)-5-phenyl-1,3,4-oxadiazole derivatives. First, we synthesized 2-methoxybenzohydrazide from methyl 2-methoxybenzoate which was treated with different arylaldehydes to afford 1–25 compounds. The synthesized compounds were evaluated for antiglycation activity. We found that 1–6(More)
Phenyl thiazole hydrazone derivatives 1–21 have been synthesized and screened for their in vitro antiglycation activity. Hydrazones 1–21 displayed assorted antiglycation activities having IC50 values in the range of 187.61 ± 1.12–886.98 ± 5.29 µM as compared to standard rutin (IC50 = 269.07 ± 3.79 µM). Compounds 5 (IC50 = 187.61 ± 1.12 µM), 3 (IC50 = 191.92(More)
Thiourea analogs 1–20 were synthesized and evaluated for their in vitro β-glucuronidase inhibitory potential. The compounds 9 (0.86 ± 0.01 μM), 6 (1.24 ± 0.01 μM), 16 (1.64 ± 0.02 μM) and 15 (2.12 ± 0.02 μM) showed potent activity. Other analogs 1–5, 7, 8, 10, 11, 13, 17, 20 showed better activity than standard drug d-saccharic acid 1,4-lactone (47.34 ±(More)
Compounds 1–30 showed varying degree of α-glucosidase inhibition with IC50 values ranging between 187 and 420 μM. Compounds 1, 2, 3, 6, 8, 12, and 4 (IC50 = 187.7 ± 3.05, 203.4 ± 4.0, 240.7 ± 1.9, 252.9 ± 3.9, 285.2 ± 6.3, 399.07 ± 1.2, and 420.36 ± 5.6 μM, respectively) were found to be more active than standard acarbose (IC50 = 906 ± 6.3 μM). The(More)
Schiff bases of 3,4-dimethoxybenzenamine 1-25 were synthesized and evaluated for their antioxidant activity. All the synthesized compounds were characterized by various spectroscopic techniques. In addition, the characterizations of compounds 13, 15 and 16 were supported by crystal X-ray determinations and their geometrical parameters were compared with(More)
