Steroid acid amides of diamino diphenyl sulfone.
For the past several years, I synthesized various new steroid compounds and steroid derivatives for chemotherapeutic purposes. The series of the steroid acid amides of diamino diphenyl sulfone included 4-cholylamino4’-amino diphenyl sulfone (B 110) and 4-desoxycholylamino 4’-amino diphenyl sulfone (Bill) which were chosen among representative members cf this group for more detailed study. A bri...
متن کاملEvaluation of polyphenylene ether ether sulfone/nanohydroxyapatite nanofiber composite as a biomaterial for hard tissue replacement
The present work is aimed at investigating the mechanical and in vitro biological properties of polyphenylene ether ether sulfone (PPEES)/nanohydroxyapatite (nHA) composite fibers. Electrospinning was used to prepare nanofiber composite mats of PPEES/nHA with different weight percentages of the inorganic filler, nHA. The fabricated composites were characterized using Fourier transform infrared ...
متن کاملTailoring the Characteristics of Poly (phenylene-ether-ether) sulfone Membrane for Efficient Glycerol/Biodiesel Separation
Poly (phenylene-ether-ether) sulfone membrane was fabricated and characterized by efficient glycerol/biodiesel separation produced from waste cooking oils trans-esterification. The membrane preparation was processed by phase inversion technique. The morphology, Physico-chemical properties and separation behavior of membranes were studied at various PPEES concentration. A uniform surface was...
متن کاملPolybenzimidazole block sulfonated poly(arylene ether sulfone) ionomers.
Novel ionomers based on polybenzimidazole block sulfonated poly(arylene ether sulfone) show excellent thermal properties. The ionic aggregation of sulfonic acid groups leads to well-developed phase separated morphology and thus high proton conductivity at wide humidity range, up to 65 mS cm(-1) at 90% relative humidity.
متن کاملProtoporphyrinogen oxidase as a molecular target for diphenyl ether herbicides.
Diphenyl ether herbicides induce an accumulation of protoporphyrin IX in plant tissues. By analogy to human porphyria, the accumulation could be attributed to decreased (Mg or Fe)-chelatase or protoporphyrinogen oxidase activities. Possible effects of acifluorfen-methyl on these enzymes were investigated in isolated corn (maize, Zea mays) etioplasts, potato (Solanum tuberosum) and mouse mitocho...
