The embodiments provide compounds of the general formulas I-XIX, as well as compositions, including pharmaceutical compositions, comprising a subject compound. The embodiments further provide treatment methods, including methods of treating flaviviral infection, including hepatitis C virus infection and methods of treating liver fibrosis, the methods generally involving administering to an individual in need thereof an effective amount of a subject compound or composition.
Basicity of nitrogen–sulphur(<scp>VI</scp>) compounds. Part 6. Ionization of NN′-di-and N-mono-substituted sulphamides and dihydro-2,1,3-benzothiadiazoline and benzothiadiazine 2,2-dioxides (cyclic sulphamides)

tri-substituted sulphamides have been synthesised and their ionization equilibria in base (Schemes 1–3) have been studied. Many of the sulphamides are new materials. The pKa values obtained for each series have been correlated in Hammett and Taft plots. The Hammett ρ values obtained for the ionization of the proximate hydrogen are ca. 2.3. The Taft ρ* value obtained for ionization of the ‘remoter’
已合成了36个二取代的,单取代的和两个三取代的磺酰胺,并研究了它们在碱中的电离平衡(方案1-3)。许多磺酰胺是新材料。在Hammett和Taft图中,已将每个系列获得的p K a值关联起来。对于邻近氢的电离获得的哈米特ρ值约为。2.3。用于“远程”氢离子化获得的Taftρ*值为1.68。六元环状磺酰胺比其无环类似物的酸性大约高出约2。2.5 p ķ一个单元和五元环sulphamides是CA。4 p K a单元比模型开放链对应单元酸性更高。硫d-轨道参与和环应变被认为是这种“增强酸”作用的可能来源。

inhibitor (CAI), sulfamide, whose X-ray crystal structure in the adduct with hCA II has recently been reported. A series of N,N-disubstituted- and N-substituted-sulfamides were prepared from the corresponding amines and N-(tert-butoxycarbonyl)-N-[4-(dimethylazaniumylidene)-1,4-dihydropyridin-1-ylsulfonyl]azanide or the unstable N-(tert-butoxycarbonyl)sulfamoyl chloride. The disubstituted compounds

An efficient and convenient one-potsynthesis of novel α-sulfamidophosphonates is described via a three-component reaction. This reaction was carried out through a three component condensation reaction of sulfonamide, an aromatic aldehyde and triethylphosphite under conventional/ultrasonic techniques, catalyst-free and solvent-free conditions. This methodology was established with many advantages,
Use of the dyestuffs of the formula ##STR1## wherein R, Y and X have the meaning given in the description, for the dyeing of synthetic textiles, especially those of aromatic polyesters, by the transfer printing process. Prints obtained are distinguished by good fastness in use properties.
