Abstract: The disclosure discloses a fatty acid synthase inhibitor and application thereof and belongs to the technical field of medical biology. The fatty acid synthase inhibitor of the disclosure can significantly inhibit the activity of fatty acid synthase without affecting normal expression, and adjust the ratio of fatty acids in cells. The fatty acid synthase inhibitor of the disclosure has a good tumor proliferation inhibitory effect, can arrest the growth cycle of tumor cells in the interphase, prevent tumor cell division, inhibit tumor cell proliferation, promote tumor cell apoptosis and exert a tumor treatment effect, can be used to treat tumors and metabolism related diseases, and has an important clinical application prospect.

Abstract: A cryostat includes a room temperature vessel, a low temperature vessel, and a refrigeration mechanism. The room temperature vessel includes a room temperature tank, an outer neck tube and a sealing head. The low temperature vessel includes a low temperature tank, an inner neck tube and a liquefaction chamber. The liquefaction chamber corresponds to the first opening and passes through the first opening. The refrigeration mechanism includes a device panel and a refrigeration device. The device panel is disposed on the sealing head. The refrigeration device includes a body and a cold finger. The body is disposed at the device panel. The cold finger is connected with the body and extends into the liquefaction chamber.
