There are disclosed novel avermectin compounds wherein the 4" or 4' hydroxy group is oxidized to an oxo group and replaced with a semicarbazone, carbonyl- or sulfonyl- hydrazone, hydrazone, or oxime, and optionally reduced to the corresponding semicarbazide, carbonyl- or sulfonyl-hydrazide or hydrazine. The semicarbozones and hydrazones are prepared from the 4" or 4' oxo compound using the corresponding semicarbazides or hydrazines. The compounds have utility as anti-parasitic agents and compounds for that use are also disclosed. The compounds are also highly potent insecticides against agricultural pests. Compositions for such uses are also disclosed.
揭示了新型阿维菌素化合物,其中4"或4'羟基被氧化成羟基酮,并替换为半卡巴肼、酰肼、磺酰肼、肼或肟,可选择还原为相应的半卡巴肼、酰肼、磺酰肼或肼。半卡巴肼和肼是从4"或4'酮化合物使用相应的半卡巴肼或肼制备的。这些化合物具有抗寄生虫剂的用途,并揭示了用于该用途的化合物。这些化合物也是高效的农业害虫杀虫剂。还揭示了用于此类用途的组合物。
