The initial compounds for the syntheses were 3-bromo-4-alkoxyphenylacetic acid hydrazides obtained using reactions between methyl esters of the corresponding acids and hydrazine hydrate [3]. The substituted benzylisothiocyanates were synthesized by reacting the corresponding benzyl chlorides with potassium rhodanate [4]. The target thiosemicarbazides I IX had the form of crystalline substances and
用于合成的初始化合物是使用相应酸的甲酯与水合肼之间的反应获得的 3-溴-4-烷氧基苯乙酸酰肼 [3]。取代的苄基异硫氰酸酯是通过相应的苄基氯与硫氰酸钾反应合成的 [4]。目标缩氨基硫脲 I IX 具有结晶物质的形式,并通过 TLC 以及红外和紫外光谱进行鉴定(表 1)。合成化合物的急性毒性试验表明,最大耐受剂量(MTD)超过 2000 mg/kg,这允许对 sar-
