Juvenile hormone B 3 (Juvenile hormone III bisepoxide) (mixture of diastereomers) 是一种倍半萜类激素。它可以从果蝇和黑腹果蝇等高等双翅目昆虫的翅体 (CA) 中分离,具有抗变态活性。Juvenile hormone B 3 (mixture of diastereomers) 通过与幼虫激素 (JH) 受体 (Met和Gce) 的直接作用,诱导Kr-h1的表达,可用于昆虫致死性研究。
LLY-284 is the diastereomer of LLY-283, which is a selective and potent SAM-competitive chemical probe for PRMT5. LLY-284 is much less active than LLY-283 and can be used as a negative control for LLY-283.
