5-Fluorouracil

CAS No. : 51-21-8

MCE 国际站：5-Fluorouracil

产品活性：5-Fluorouracil (5-FU) 是一种尿嘧啶的类似物 (nucleoside antimetabolite/analog)，是一种有效的抗肿瘤药。5-Fluorouracil 通过抑制胸苷酸合成酶影响嘧啶的合成，从而耗尽细胞内dTTP 池。5-Fluorouracil 诱导细胞凋亡 (apoptosis)，可用作化学敏化剂。5-Fluorouracil 还可抑制 HIV 病毒。5-Fluorouracil (5-FU) 可破坏外泌体特异性的 rRNA。

研究领域：Cell Cycle/DNA Damage  |  Anti-infection  |  Apoptosis  |  Metabolic Enzyme/Protease

作用靶点：Nucleoside Antimetabolite/Analog  |  HIV  |  Apoptosis  |  Endogenous Metabolite

In Vitro: 5-Fluorouracil (5-Fu) and NSC 123127 (Dox) show synergistic anticancer efficacy. The IC₅₀ value of 5-Fu/Dox-DNM toward human breast cancer (MDA-MB-231) cells is 0.25 μg/mL, presenting an 11.2-fold and 6.1-fold increase in cytotoxicity compared to Dox-DNM and 5-Fu-DNM, respectively. In 5-fluorouracil (5-FU) and CDDP treated NFBD1-inhibited NPC cells, the NFBD1 expression in NPC CNE1 cell lines is depleted using lentivirus-mediated short hairpin RNA, and the sensitivity of these cells is elevated. NFBD1 knockdown leads to an obvious induction of apoptosis in CDDP- or 5-FU-treated CNE1 cells.

In Vivo: 5-Fluorouracil (23 mg/kg, 3 times/week) for 14 days, induces accelerated gastrointestinal transit associated with acute intestinal inflammation at day 3 after the start of treatment, which may have led to persistent changes in the ENS observed after days 7 and 14 of treatment contributing to delayed gastrointestinal transit and colonic dysmotility.
