生物活性 Menaquinone-4 是一种维生素 K,用作一种止血剂,用于治疗骨质疏松的辅助治疗。[1-2]
In Vitro 甲基萘醌-4(MK-4,0,1,5,10μM)增加Caco-2细胞中的ALP活性。甲基萘醌-4(1μM)显著增加hSI表达的强度[1]。
In Vivo HF-K2组中的甲基萘醌-4(K2,0.2g/kg饮食)在C57BL/6J小鼠中产生附睾脂肪,并且还增加小鼠的骨密度[2]。

靶点 Others
动物实验 42只雄性,4周龄的C57BL/6J小鼠随意提供饲料和饮料。对于环境适应,动物有1周的循环,然后在随机分成6组(每组7只动物;随机区组设计)后提供实验饮食。 AIN-93G饮食包括正常饮食(N),正常饮食+维生素K1(N-K1),正常饮食+维生素甲萘醌-4(N-K2),45%高脂饮食(HF),45%高脂肪饮食+维生素K1(HF-K1),45%高脂饮食+维生素甲萘醌-4(HF-K2)。维生素K1和维生素甲基萘醌-4含量为200mg/1,000g,饮食以颗粒形式提供。每周测量一次体重,并且通过将实验期间的食物摄入量除以第1天至最后一天的增加的体重来计算食物效率比(FER)。对于脂肪量测量,从死亡动物受试者中提取附睾脂肪,肾周脂肪和腹膜后脂肪,用0.9%NaCl洗涤,用滤纸干燥,然后称重[2]。
细胞实验 将Caco-2细胞以2-5×10 4个细胞/ cm 2的密度接种到35-mm培养皿上。将细胞温育2至3天直至60%-70%汇合,并加入所需浓度的甲基萘醌-4(0,1.0,5.0和10.0μM)。载体的最终浓度为培养基的0.1%,培养基每周更换两次。在添加Menaquinone-4 [1]后第0,3,7和11天测定细胞。

生物活性 Treatment of embryo-recipient mares with altrenogest appears to be beneficial in extending the degree of donor-recipient synchrony required for successful embryo transfer. Altrenogest treatment also seems to be conductive to pregnancy maintenance in recipients experiencing luteal dysfunction.[1]
In Vitro Altrenogest (Allyltrenbolone) is a progestogen structurally related to veterinary steroid trenbolone. Treatment of embryo-recipient mares with Altrenogest (Allyltrenbolone) appears to be beneficial in extending the degree of donor-recipient synchrony required for successful embryo transfer[1]. The oil and gel Altrenogest (Allyltrenbolone) preparations are equally effective in modulating estrous behavior and time to estrus and ovulation. Altrenogest (Allyltrenbolone) treatment started late in diestrus appears to result in a high incidence of ovulation during treatment and when luteolysis and ovulation occur during treatment; the subsequent luteal phase is frequently prolonged due to failure of regression of the CL[2].

细胞实验 The response to 15-d altrenogest treatment (Experiment 1) was characterized in 20 mares that were given 22 mg daily of altrenogest in oil (n = 10) or in gel (n = 10) from Day 10 to 25 after ovulation. [2]
