Catalog No. TQ0141Cas No. 228266-40-8
Alias SPA-110, HTI-286

Taltobulin (HTI-286) is a synthetic analog of the tripeptide cysteine, a microtubule protein inhibitor that inhibits liver tumor cell proliferation in vitro and tumor growth in vivo.Taltobulin is cytotoxic, induces mitotic arrest and apoptosis, and may be used in the study of breast cancer and microtubule tissue-related diseases.

Product Introduction

Bioactivity
Description
Taltobulin (HTI-286) is a synthetic analog of the tripeptide cysteine, a microtubule protein inhibitor that inhibits liver tumor cell proliferation in vitro and tumor growth in vivo.Taltobulin is cytotoxic, induces mitotic arrest and apoptosis, and may be used in the study of breast cancer and microtubule tissue-related diseases.
In vitro
In leukemia CCRF-CEM cell line, ovarian 1A9 cell line, non-small cell lung cancer A549 cell line, and NCI-H1299 cell line, Taltobulin (0.2-7.3 nM; 3 days) inhibited the growth of tumor cell lines with IC50 values of 0.2±0.03 nM, 0.6±0.1 nM, 1.1±0.5 nM, and 6.8±6.1 nM, respectively[1].
In vivo
In athymic nu/nu female mice with Lox melanoma model (5-6 weeks of age), treatment with Taltobulin (1.6 mg/kg; administered i.v.; for 35 days) resulted in a 96-98% inhibition of Lox tumor growth on day 12 compared to the control group[1].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
