A series of triazin-3(2H)-one derivatives bearing 1,3,4-oxadiazole (4a-4o) were synthesized, characterized and evaluated for anti-inflammatory and analgesic activities. Preliminary in vitro anti-inflammatory activity was assessed using an albumin denaturation assay. The promising compounds were further evaluated in acute, sub-chronic and chronic animal(More)
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)
Malaria is a global health problem that needs attention of drug discovery scientists to investigate novel compounds with high drug efficacy, safety and low cost to counter the malaria parasites that are resistant to existing drug molecules. This is an overview of past to present status of antimalarial drugs including newly researched candidates and also the(More)
The colon specific polymeric conjugates of celecoxib were prepared with dextran of different molecular weight Mr approximately 40 000, 70 000, and 100 000 (CSD-40, CSD-70 and CSD-100). Succinic acid was used as linker between the drug and dextran. The prepared conjugates were characterized by UV, IR, 1H NMR and HPLC. The maximum degree of substitution(More)
In the present study substituted 1,2-naphthoquinones were synthesized, purified and characterized by spectroscopic studies (UV, FT-IR, ¹H NMR, ¹³ C NMR and elemental analysis). These compounds were evaluated for cytotoxicity against a panel of human cancer cell lines (Hep-G₂ for liver sarcoma, MG-63 for osteosarcoma and MCF-7 for human breast cancer). The(More)
Solid- phase synthesis is an approach, where synthetic transformation in carbohydrates are carried out with one of the reactant molecule attached to an insoluble material referred as polymeric support via linker. In recent years, it has been extensively accepted as fast and accurate method for the synthesis of biologically active oligosaccharides. This(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)
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)
In an attempt to develop potent anticancer agents, a series of 4-arylideneamino/cycloalkylidineamino-1, 2-naphthoquinone thiosemicarbazones were synthesized and characterized using FT-IR, (1)H NMR, (13)C NMR spectroscopy and elemental analysis. The compounds were screened for antiproliferative activity against three human cancer cell lines (Hep-G2, MG-63(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)
