BACKGROUND Hypersensitivity (HS) reactions to sulfonamide antibiotics occur uncommonly, but with potentially severe clinical manifestations. A familial predisposition to sulfonamide HS is suspected, but robust predictive genetic risk factors have yet to be identified. Strongly linked genetic polymorphisms have been used clinically as screening tests for other HS reactions prior to administratio...

Cytochrome P450 2C9-mediated metabolism has been shown to be activated in the presence of the effector dapsone. However, it has yet to be established what effector structural features are necessary to activate CYP2C9 activity. To address this question, kinetic studies were conducted with nine analogs of dapsone containing various functional properties (three sulfone compounds, three carbonyl co...

To explore the anticancer activity of 2, 4, 5, 6-substituted pyrimidines, several ethyl 2-(1-aminocyclobutyl)-5-(benzoyloxy)-6-hydroxy-pyrimidine-4-carboxylate derivatives associated with the different substituted aromatic/aliphatic carboxamides and sulfonamides were synthesized. Different groups and position on phenyl ring attached to the carboxamide and sulfonamide of the pyrimidine led to tw...

A series of sulfonamide compounds, para-aminohippurate, and inulin were used to study the permeability of the epithelium of human sweat glands. Inulin was not excreted in the sweat. The ratios of the concentrations in sweat to the concentrations in plasma, S/P, of sulfanilamide, sulfapyridine, sulfathiazole, sulfadiazine, and para-aminohippurate were found to be 0.69, 0.58, 0.13, 0.11, and 0.02...

An efficient synthesis of two series of novel carbamate and sulfonamide derivatives of amlodipine, 3-ethyl 5-methyl 2-(2-aminoethoxy)-4-(2-chlorophenyl)-1,4-dihydropyridine-3,5-dicarboxylate (Amlodipine) 1 was accomplished. Various chloroformates 2(a-e) and sulfonyl chlorides 4(a-e) on reaction with 1 in the presence of N,N– dimethylpiperazine as a base in THF at 50-55 C yielded the correspondi...

Sulfonamide drugs which have brought about an antibiotic revolution in medicine are associated with a wide range of biological activities. We have synthesized a series of α-tolylsulfonamide, 1-11 and their substituted N,N-diethyl-2-(phenylmethylsulfonamido) alkanamide derivatives, 12-22 in improved and excellent yields in aqueous medium at room temperature through highly economical synthetic ro...

A series of carboxylate compounds were prepared from N(alpha)-substituted 2,3-diaminopropionic acid and were tested for efficacy as matrix metalloproteinase (MMP) inhibitors. During modeling of the initial compound 10a, we utilized three-dimensional structure modeling software (InsightII/Discover Ver. 2.98). Some of the prepared carboxylate derivatives, such as carbamate compounds (12c,d, 22) a...

In the title compound, C(17)H(21)N(3)O(4)S(2), an intra-molecular N-H⋯O hydrogen bond involving the proximate amine and nitro groups is observed. In the crystal, inter-molecular N-H⋯O hydrogen bonds involving the amine and SO(2) groups occur. One of the notro O atoms is disordered over two conformations with occupancies of 0.578 (12) and 0.422 (12).

In the title compound, [Zn(C(17)H(14)Cl(2)N(3)O(3)S)(2)(H(2)O)(2)], the Zn(II) ion has a tetra-hedral coordination formed by the two N atoms of the sulfonamide groups and the two water mol-ecules. Two inter- and two intra-molecular O-H⋯O hydrogen bonds are observed in the crystal structure.

Background: Volatile organic compounds (VOC) are considered as major environmental contaminants that have a harmful effect on human and ecosystem health, so much effort has been focused on their removal. The aim of this study was to investigate the removal efficiency of styrene by Zeolite Socony Mobil-5 (ZSM-5) after immobilization of nanoparticles of zinc oxide (ZnO) on it. Materials and Meth...
