    Synthesis, anticancer activity and ADMET studies of N-(5-methyl-1,3,4-thiadiazol-2-yl)-4-[(3-substituted)ureido/thioureido] benzenesulfonamide derivatives
    (TAYLOR & FRANCIS LTD, 2018) KAYMAKÇIOĞLU, BEDİA; Karakus, S.; Tok, F.; Tuerk, S.; Salva, E.; Tatar, G.; Taskin-Tok, T.; Kocyigit-Kaymakcioglu, B.
    A series of novel 4-[(3-substituted)ureido]-N-(5-methyl-1,3,4-thiadiazol-2-yl) benzenesulfonamides and 4-[(3-substituted)thioureido]-N-(5-methyl-1,3,4-thiadiazol-2-yl)benzenesulfonamides were prepared from 4-amino-N-(5-methyl-1,3,4-thiadiazol-2-yl)benzenesulfonamide (sulfamethizole). The structures of the synthesized compounds were determined by IR, H-1-NMR, MS and elemental analysis. The anticancer activity of these compounds was evaluated against human colorectal carcinoma (HCT116) and human cervix carcinoma (HeLa) cell lines. Compound 4 (4-{[(2,4-dichlorophenyl)carbamoyl]amino}-N-(5-methyl-1,3,4-thiadiazol-2-yl)benzenesulfonamide) showed marked anticancer activity, being the most active compounds in this series with the IC50 value of 13.92 +/- 0.22 mu M and 37.91 +/- 0.10 mu M against HeLa and HCT116, respectively. In silico, ADMET was used to examine their pharmacokinetic properties. ADMET (absorption, distribution, metabolism, excretion, and toxicity) studies were applied to develop new anticancer compound(s) with high selectivity. [GRAPHICS] .

    Synthesis and Anticonvulsant Activity of New N-(Alkyl/Substituted aryl)-N '-[4-(5-cyclohexylamino)-1,3,4-thiadiazole-2-yl)pheny]thioureas
    (WILEY-V C H VERLAG GMBH, 2009) KAYMAKÇIOĞLU, BEDİA; Karakus, Sevgi; Kocyigit-Kaymakcioglu, Bedia; Toklu, Hale Z.; Aricioglu, Feyza; Rollas, Sevim
    A series of novel thiourea derivatives carrying the 5-cylohexylamino-1,3,4-thiadiazole moiety was synthesized and their anticonvulsant activity was evaluated. Structures of the synthesized compounds have been confirmed by IR, H-1-NMR, and elemental analysis. All of the compounds were administered at a dose of 50 mg/kg. Some of the active compounds have different effects in pentylenetetrazole (PTZ) and maximal electroshock (MES) tests, indicating the therapeutical potential in petit mal seizures, but not in grand mal seizures. Compounds 10, 11, 13, and 14 carrying 2-methylphenyl, 4-chlorophenyl, allyl, and 4-methylphenyl on the thiourea pharmacophore, increased the survival rate in the PTZ model. The ED50 values of the active compounds 10, 11, 13, and 14 were found 68.42, 43.75, 18.75 and 25 mg/kg, respectively.
