1,2,4-Oxadiazoles having as 3- and 5-substituents a hydrogen atom, an aliphatic, cycloaliphatic, araliphatic, aryl or heterocyclic group, or a carbamoyl group of the formula -- CONR.sup.1 R.sup.2 where R.sup.1 & R.sup.2 which can be the same or different, are hydrogen atoms or aliphatic, cycloaliphatic, araliphatic or aryl groups or, taken with the N atom, a heterocvolic ring; provided that at least one of the 3- or 5-substituents is an N-substituted carbamoyl group. Antimicrobial activity, and particularly antiviral, antiparasitic and antibacterial activity is shown in this group. The corresponding oxadiazolins are also described and are useful intermediates in the preparation of the oxadiazoles.
具有1,2,4-噁二唑骨架的化合物,在其3-和5-位上可以有氢原子、脂肪族、环脂族、芳基或杂环基团,或者是公式为--CONR.sup.1 R.sup.2的氨基甲酰基团,其中R.sup.1和R.sup.2可以相同也可以不同,可以是氢原子或脂肪族、环脂族、芳基或与N原子结合形成杂环的基团;但至少一个3-或5-位上的取代基是N-取代的氨基甲酰基团。此类化合物表现出抗微生物活性,特别是抗病毒、抗寄生虫和抗菌活性。对应的噁二唑环酮也被描述,并且是制备噁二唑化合物的有用中间体。
