Anal fissure is an ischemic ulcer that occurs in anoderm and it has no obvious etiology and pathophysiology in current medicine. Anal fissure has a profound history in Persian and Persian medicine and wallflower (Erysimum cheiri (L.) Crantz) has been a common medication in this case. Traditional oil and/or dilute decoction of wallflower has been introduced as an effective topical medic...
New 1,3,4-thiadiazole, 6, 7 and 1,2,4-triazole derivatives, 8, 9 containing a phenylalanine moiety have been synthesized by intramolecular cyclization of 1,4-disubstituted thiosemicarbazides, 4, 5, in acid and alkaline media, respectively; the thiosemicarbazides were obtained by reaction of hydrazide 3 with appropriate aromatic isothiocyanates. The toxicity of the synthesized compounds was eval...
A series of novel bis(substituted pyrazol-4-ylcarbonyl)-substituted thioureas have been synthesized by the reactions of substituted pyrazol-4-ylcarbonyl isothiocyanates with different diamines under ultrasound irradiation and classical heating method at 20-25 degrees C. In general, substantial improvement in rates and modest yields increases were observed when reactions were carried out under s...
