Mutual prodrugs consisting of mefenamic acid with menthol and thymol have been synthesized as a gastrosparing NSAIDs, devoid of ulcerogenic side effects. The structures of synthesized esters were confirmed by IR, 1H NMR, and mass spectroscopy. The kinetics of ester hydrolysis was studied in nonenzymatic buffer solutions, at pH 2 and 7.4 as well as in human(More)
A series of Schiff bases of 4-amino-1,2-naphthoquinone were synthesized, purified, characterized, and evaluated for cytotoxicity against a panel of human cancer cell lines (Hep-G2, MG-63, and MCF-7). The cells were dosed with these Schiff bases at varying concentrations, and cell viability was measured by a(More)
Substituted piperazine and aniline derivatives of oxazolidin-2,4-diones and imidazolidin-2,4-diones were synthesized by N3 alkylation and screened for their anticonvulsant activity by the maximal electroshock (MES) test, and their neurotoxicity was evaluated by the rotarod test. Among all the synthesized derivatives, compounds 4b, 6c, 6d, 10b, 11a, 11b, and(More)
Different derivatives of fluoroquinolones were synthesized by combining it with different thiadiazoles. The synthesized compounds were characterized by infrared spectroscopy, proton nuclear magnetic resonance and mass spectral data. The compounds were screened for their antibacterial and antifungal activity. Ciprofloxacin derivatives with thiadiazoles 7c(More)
A novel series of thiazolidine-2,4-diones was designed, synthesized and investigated for anti-diabetic activity. The (2,4-dioxo-1,3-thiazolidin-5-yl)methylphenylbenzamide derivatives contain an amide linkage between the central aryl ring and the hydrophobic tail. Structures of the compounds were confirmed by spectroscopic techniques fourier transform(More)
Certain novel 3-aryl/heteroaryl-substituted 2-(2-chlorostyryl)-6,7-dimethoxy-quinazolin-4(3H)-one (5a–5l) derivatives have been synthesized and evaluated for their anticonvulsant activity against maximal electroshock (MES)-, subcutaneous pentylenetetrazole (scPTZ)- and intracerebroventricular (icv) AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic(More)
Some new semicarbazones of 4-aminopyridine were synthesized and evaluated for antiamnesic, cognition enhancing and anticholinesterase activities. The results illustrated a significant cognition enhancing effect on elevated plus maze model with a significant reversal of scopolamine-induced amnesia. A significant inhibition in acetycholinesterase (AChE)(More)
Some new anilide and imide derivatives of 4-aminopyridine (4AP) were synthesized and evaluated against antiamnesic, cognition enhancing and anticholinesterase activity through their respective in vitro and in vivo models. These newly synthesized derivatives have illustrated an enhanced cognition effect on elevated plus maze model and also demonstrated a(More)
The aim of this review is to provide an overview on diverse pharmacological activities of the benzimidazole moiety. This review highlights recent reports of antimicrobial, anticancer, antiviral, antiparasitic, antihypertensive as well as anti-inflammatory activities of the benzimidazoles. The purpose of this review is to collate the literature work reported(More)
4-Aminopyridine (4AP) potentiates acetylcholine (ACh) release by blocking potassium channel in axon terminal and can be used in the treatment of Alzheimer’s type of dementia and cognitive disorder. It is reported that ACh is well related with memory and learning. On the basis of these fact, we decided to synthesis and evaluate some new Schiff bases of 4AP(More)
