A new series of (benzofuran-2-yl)-1-phenyl-1H-pyrazol-4-yl) pyrimidine derivatives were synthesized from 3-(benzofuran-2-yl)-1-phenyl-1H-pyrazol-4-carbaldehyde (1) through different routes of cyclocondensation reactions. Condensation of 1 with active methylene compounds afforded compounds 2-8. The cyclization of 2 with chloroacetic acid, ortho substituted(More)
Herein, novel hybrid compounds of celecoxib and 2-aminoanthraquinone derivatives have been synthesized using condensation reactions of celecoxib with 2-aminoanthraquinone derivatives or 2-aminoanthraquinon with celecoxib derivatives. Celecoxib was reacted with different acid chlorides, 2-chloroethylisocyanate and bis (2-chloroethyl) amine hydrochloride.(More)
The reaction of 5-(1-adamantyl)-4-ethyl or allyl-1,2,4-triazoline-3-thione with formaldehyde solution and various 1-substituted piperazines yielded the corresponding N-Mannich bases. The newly synthesized N-Mannich bases were tested for in vitro inhibitory activities against a panel of Gram-positive and Gram-negative bacteria and the yeast-like pathogenic(More)
A new series of novel substituted 3,4-dihydronaphthalene incorporated to benzo[h]quinoline, benzo[g]indazole, thiazolidin-4-one, pyrazolo[3,4-d]thiazol and thiazolo[4,5-b]pyridine ring systems were synthesized and evaluated for their cytotoxicity against selected human cancer cell lines. Some of the tested compounds exhibited promising carcinoma growth(More)
A facile, convenient and high yielding synthesis of novel S-glycosides and N-glycosides incorporating 1,2,3,4-tetrahydronaphthalene and or 1,2-dihydropyridines moieties has been described. The aglycons 2, 4, and 7 were coupled with different activated halosugars in the presence of basic and acidic medium. The preliminary in-vitro cytotoxic evaluation(More)
In continuation of our previous work, a novel series of polycyclic derivatives 2-8 incorporated heterocyclic and sugar moieties were synthesized by using pyren-1-aldehyde (1) as starting material and their tested as antiviral activities. Initially, the toxicity of the compounds was assayed via the determination of their EC(50). Some of the synthesized(More)
Some N-p-substituted phenyl uracil-5-sulphonamide derivatives have been synthesized to be evaluated as molluscicides against Biomphalanaria alexandrina snails, the intermediate host of Schistosoma mansoni. Schistosoma mansoni infected mice were treated with hemolymph obtained from pre-treated Biomphalana alexandrina snails with the products 4a, 10a, 10b and(More)
A new series of 1,2,3,4-tetrahydronaphthalen-6-yl-thiazole and thiazolidinone derivatives were synthesized. Twenty four of the newly synthesized compounds were evaluated for their anti-inflammatory and analgesic activity. The study exhibited that the derivatives 7b and 11c produced equipotent anti-inflammatory activity to that of the reference drug(More)
A novel series of cyanopyridinyl tetrahydronaphthalene incorporated with different heterocycles were synthesized. The key compounds 2a,b were condensed with chloroacetone and ethyl chloroacetate to give 3a,b and 4a,b, respectively. Also condensation of 4a,b with hydrazine hydrate gave the corresponding hydrazide 5a,b. Reaction of 5b with different(More)
