menaquinone-4

Menaquinone-4 (Vitamin K2) 是维生素 K 的一种，用作止血剂，有潜力用于骨质疏松的研究。

Menaquinone 4-d7 (Mixture of cis-trans isomers) 是 Menaquinone 4 (Mixture of cis-trans isomers) 的氘代化合物。

Boromycin is a boron-containing macrolide antibiotic that has been found in Streptomyces. Boromycin inhibits growth of B. subtilis (MIC = 0.05 μg ml) and induces efflux of potassium ions from B. subtilis without affecting Na+ K+-ATPase activity. It decreases the synthesis of protein, RNA, and DNA in B. subtilis when used at a concentration of 0.05 μg ml. It inhibits the growth of B. halodurans (MIC = 10 ng ml) and inhibits the futalosine pathway of menaquinone synthesis in B. halodurans. Boromycin (3.4 nM) reverses bleomycin-induced cell cycle arrest at the G2 phase in Jurkat cells. It inhibits replication of the HIV-1 strains LAV-1 and RF and the HIV-2 strain LAV-2 in MT-4 cells (IC50s = 0.008, 0.11, and 0.007 μM, respectively). It also inhibits replication of a clinical isolate of HIV-1, strain KK-1, in MT-4 cells and peripheral blood mononuclear cells (PBMCs; IC50s = 0.14 and <0.1 μM, respectively).

MK7-d7 是 MK7 的氘代化合物。MK7 的 CAS 号为 2124-57-4。Menaquinone-7 是一种最早作为抗出血因子被发现的维生素K2家族成员。它是Gla-蛋白羧化反应中最具生物活性的辅因子，补充它也是激活Gla基质蛋白并干预钙化性主动脉瓣狭窄(CAVS)进展的一种药理选择。
