Lanreotide diTFA

Lanreotide (BIM 23014) diTFA is a somatostatin analogue with antineoplastic activity. Lanreotide diTFA can be used for the research of carcinoid syndrome[1][2].

Lanreotide (BIM 23014) (100  nM; 0-48 h) enhanced radiation-induced apoptosis[1]. Lanreotide results in a dose-dependent decrease in GH3 cell colony forming units. Lanreotide at concentrations of 1, 10, 100, and 1000 nM results in cell survival rates of 75, 56, 39 and 27% respectively. The IC50 is 57 nM[1]. Lanreotide inhibits GH-secreting pituitary adenoma cell proliferation and hormone release in vitro[2]. Apoptosis Analysis[1] Cell Line: GH3 Concentration: 100 nM Incubation Time: 48 h, 24 h, or immediately (0 h) before radiation Result: Increased apoptotic sub-G1 proportion compared with radiation alone.

Lanreotide (2.5-10mg/kg; s.c.; daily for 5 days) results in tumor growth inhibition[1]. Animal Model: Male nude mice, 8 weeks old and 20–25 g in body weight (GH3 tumor-bearing nude mice)[1] Dosage: 2.5, 5, 10 mg/kg Administration: Subcutaneous; daily for 5 days Result: Produced tumor growth inhibition.
