生物活性:
KRN5500 (NSC 650426), a Spicamycin (HY-127130) derivative and a nucleoside-like antibiotic with anti-tumor activity. KRN5500 also induces apoptosis via the down-regulation of Bcl-2 expression. KRN5500 shows a significant efficacy in the human tumor xenograft model in mice.

体内研究:
KRN5500 (4 mg/kg; 腹腔注射; 每天 1 次,共 5 天) 显示抗肿瘤活性,导致一些小鼠肿瘤和人肿瘤异种抑制模型中的肿瘤重量下降。Animal Model:Mouse model with murine tumors and human tumor xenografts
Dosage:4 mg/kg
Administration:Intraperitoneal injection; once daily for 5 days
Result:Prolonged the survival of P388 leukemia- and B16 melanoma-bearing mice but lacked marginally effective on colon adenocarcinoma.Decreased tumor weight in 10 human stomach, 14 colon and 2 esophageal cancers.

体外研究:
KRN5500 (10-160 ng/mL; 0-5 d) 有效抑制 NB4、NKM-1 和 HL-60 细胞的增殖和活力。KRN5500 (40 ng/mL, 160 ng/mL; 48 h) 诱导 NB4、HL-60 和 NKM-1 细胞凋亡。KRN5500 (40 ng /mL, 80 ng /mL; 36 h) 下调 NB4 细胞中 Bcl-2 的表达。
