Novel derivatives of quinazoline (1-27) have been synthesized and tested for their antitumor activity against three tumor cell lines among these cell lines the human breast carcinoma cell line (MCF-7) in which EGFR is highly expressed. All tested compounds showed potent and selective activity against breast cancer (MCF-7) with IC(50) range of 3.35-6.81(More)
New arylhydrazone derivatives and a series of 1,5-diphenyl pyrazoles were designed and synthesized from 1-(4-chlorophenyl)-4,4,4-trifuorobutane-1,3-dione 1. The newly synthesized compounds were investigated in vivo for their anti-inflammatory activities using carrageenan-induced rat paw oedema model. Moreover, they were tested for their inhibitory activity(More)
New pyrazole and pyrazoline derivatives have been synthesized and their ability to inhibit ovine COX-1/COX-2 isozymes was evaluated using in vitro cyclooxygenase (COX) inhibition assay. Among the tested compounds, N-((5-(4-chlorophenyl)-1-phenyl-3-(trifluoromethyl)-1H-pyrazol-4-yl)methylene)-3,5-bis(trifluoromethyl)aniline 8d exhibit optimal COX-2(More)
A new series of 4-substituted 3-methyl-1,5-diphenyl-1H-pyrazoles 4–11 has been synthesized and evaluated for its in vitro antiviral activity and cytotoxicity against herpes simplex virus type-1 grown on Vero African green monkey kidney cells through plaque-reduction assay method using acyclovir as a positive control. The synthesis was achieved through(More)
A novel series of 3-benzyl-substituted-4(3H)-quinazolinones were designed, synthesized and evaluated for their in vitro antitumor activity. The results of this study demonstrated that 2-(3-benzyl-6-methyl-4-oxo-3,4-dihydroquinazolin-2-ylthio)-N-(3,4,5-trimethoxyphenyl)acetamide,(More)
New series of 6-(arylthio)uracils, 6-(4-substituted-1-piperazinyl)uracils, 2,4,5-trioxo-1H,3H-benzothiopyrano[2,3d]pyrimidine and 5-aryl-2,4-dioxo-1H,3H-pyrimido[5,4-f]benzo[1,4]thiazepines have been prepared and screened for their in vitro activity against herpes simplex-1 virus (HSV-1) and human immunodeficiency virus-1 (HIV-1). The in vitro cytotoxic(More)
A new series of 2-substituted mercapto-4(3H)-quinazolinone 1-26 were synthesized and assessed for in vivo anti-inflammatory and analgesic activities and in vitro inhibition of cyclooxygenase COX-1/COX-2. A new series of 2-substituted mercapto-4(3H)-quinazolinone 1-26 were synthesized and assessed for in vivo anti-inflammatory and analgesic activities. The(More)
Carboxylic acid imides 1–26 have been synthesized and screened for their antibacterial against gram-positive and gram-negative organisms and their antitumor activity against 60 tumor cell lines taken from nine different organs. Compounds 12, 14, and 16 were the most active and broad-spectrum antibacterial member in this study. Compound 9 showed the most(More)
A series of 2-(arylidene)-1-(4-chlorophenyl)-4,4,4-trifluorobutane-1,3-diones (2-4), 4-(arylidene)-3-(4-chlorophenyl)-5-(trifluoromethyl)-4H-pyrazoles (5-7), 1-(4-chlorophenyl)-4,4,4-trifluoro-2-(2-(aryl)hydrazono)butane-1,3-diones (8, 9), 3-(4-chlorophenyl)-4-(2-(aryl)hydrazono)-5-(trifluoromethyl)-4H-pyrazoles (10, 11),(More)
New curcumin analogues have been synthesized and their antioxidant activities were investigated by measuring their free radical scavenging capacities. The in vitro and in vivo antitumor activities of the synthesized compounds on Ehrlich ascites carcinoma (EAC) cell line were evaluated.(More)
