LTB3 is the LTA hydrolase metabolite of LTA3 in the leukotriene biosynthetic pathway. LTB3 and LTB4 are equipotent in their pro-inflammatory effects. However, LTB3 is five times less potent than LTB4 in eliciting chemotaxis of human neutrophils.
Thromboxane B3 (TXB3), the stable hydrolysis product of TXA3, is synthesized from eicosapentaenoic acid (EPA) through the action of COX and thromboxane synthase enzymes. This compound is biosynthesized in several tissues, including seminal vesicles, lungs, polymorphonuclear leukocytes (PMNL), and ocular tissues.
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。
