Vitamin K1 is a fat-soluble, dietary nutrient that is essential for the synthesis of proteins important for blood-clotting, bone metabolism, and cell growth.1 It is found in the photosynthetic tissues of green, leafy plants, where it acts as an electron acceptor forming part of the electron transport chain of Photosystem I.2 Vitamin K1 also serves as a precursor to vitamin K2 and is reported to exhibit anticancer activity in various cell lines.3,4

Cell experiment: |
Caco-2, HT-29, and SW480 cells are treated with increasing concentrations of vitamin K1 (10, 50, 100, and 200 μM) for 24 h, 48 h, and 72 h. MTT is added to each dish and incubated for 2 h at 37°C. At the end of the incubation period, the medium is removed. The plate is read at 570 nM[2]. |

Animal experiment: |
Rats: For inducing full-thickness wound in rats, the excisional wound model is used. Five groups consisting of 8 rats each are used. Vitamin K cream (1% and 2%, w/w) is prepared in eucerin base and applied on the wound once a day until complete healing had occurred. Healing is defined by decreased wound margin (wound contraction), re-epithelialization, tensile strength and hydroxyproline content. Histopathological examination is also done[5]. Mice: Four-week-old C57BL/6J male mice are fed a 10% fat normal diet group or a 45% kcal high-fat diet group, with or without 200 mg/1000 g vitamin K1 (Normal diet + K1, high-fat diet + K1) and 200 mg/1000 g vitamin K2 (Normal diet + K2, high-fat diet + K2) for 12 weeks[4]. |

工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
