吸收、分配和排泄
维生素K,主要是维生素K1形式,主要从空肠和回肠吸收。... 维生素K以由胆盐和其他物质形成的微粒形式被输送到肠细胞中。维生素K以乳糜微粒的形式由肠细胞分泌到淋巴中。它通过胸导管进入循环系统,并以乳糜微粒残余的形式被输送到包括肝脏、骨骼和脾脏在内的各种组织中。在肝脏中,部分维生素K被储存,部分被氧化成无活性的终产品,还有部分与VLDL(极低密度脂蛋白)一起被分泌。大约50%的维生素K以VLDL的形式存在于血浆中,约25%在LDL(低密度脂蛋白)中,约25%在HDL(高密度脂蛋白)中。/维生素K/
Vitamin K, mainly in the form of vitamin K1, is principally absorbed from the jejunum and ileum. ... Vitamin K is delivered to the enterocytes in micelles formed from bile salts and other substances. Vitamin K is secreted by enterocytes into the lymphatics in the form of chylomicrons. It enters the circulation via the thoracic duct and is carried in the circulation to various tissues including hepatic, bone and spleen, in the form of chylomicron remnants. In the liver, some vitamin K is stored, some is oxidized to inactive end products and some is secreted with VLDL (very low density lipoprotein). Approximately 50% of vitamin K is carried in the plasma in the form of VLDL, about 25% in LDL (low-density lopoprotein) and about 25% in HDL (high-density lipoprotein). /Vitamin K/

细菌在下肠中产生维生素K的甲萘醌形式,这些形式在那里大量出现。然而,它们对维持维生素K状态的作用一直难以评估。尽管含量极其多变,但人肝中含有的维生素K是作为甲萘醌混合物的约10倍于作为叶绿醌的量。/甲萘醌/
Menaquinone forms of vitamin K are produced by bacteria in the lower bowel, where the forms appear in large amounts. However, their contributuion to the maintenance of vitamin K status has been difficult to assess. Although the content is extremely variable, the human liver contains about 10 times as much vitamin K as a mixture of menaquinones than as phylloquinone. /Menaquinones/

    摘要:
    肝细胞癌(HCC)由于即使在治愈后仍非常频繁地复发,因此预后较差。因此,强烈需要有效且安全的长期化学预防剂。Menahydroquinone-4(MKH)是Menaquinone-4(MK-4,维生素K 2)的一种活性形式,它参与肝脏中维生素K依赖性蛋白的合成。我们假设有效递送MKH可能对调节HCC增殖至关重要。在递送和激活方面发现合适的靶向HCC的前药可以减少MK-4的临床剂量并使疗效和安全性最大化。我们以前表明,MKH二甲基甘氨酸盐(MKH-DMG)能够将MKH有效递送到HCC细胞中,并且与MK-4相比具有较强的抗肿瘤作用。在这项研究中,我们除了制备阳离子MKH-DMG外,还制备了阴离子MKH半琥珀酸酯(MKH-SUC)和非离子乙酸MKH乙酸酯(MKH-ACT),并评估了MKH的递送特性和体外抗肿瘤作用。在所检查的化合物中,MKH-SUC显示出最高的摄取和最有效的MKH释放,并显示出快
