Summary
Taltobulin hydrochloride (HTI-286 hydrochloride), a synthetic analogue of the tripeptide hemiasterlin, is a potent antimicrotubule agent that circumvents P-glycoprotein-mediated resistance in vitro and in vivo. Taltobulin hydrochloride inhibits the polymerization of purified tubulin, disrupts microtubule organization in cells, and induces mitotic arrest, as well as apoptosis [1] .

In Vitro
Taltobulin (HTI-286; 0.2-7.3 nM; 3 days) inhibits the growth of 18 tumor cell lines (leukemia, ovarian, NSCLC, breast, colon, and melanoma cell lines) with an average IC 50 of 2.5±2.1 nM and a median value of 1.7 nM [1] .
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Cell Proliferation Assay [1]
| Cell Line: | Leukemia CCRF-CEM cell line; ovarian 1A9 cell line; NSCLC A549 and NCI-H1299 cell lines; breast MX-1W and MCF-7 cell lines; colon HCT-116, DLD-1, Colo205, KM20, SW620, S1, HCT-15 and Moser cell lines; melanoma A375, Lox and SK-Mel-2 cell lines |
| Concentration: | 0.2-7.3 nM |
| Incubation Time: | 3 days |
| Result: | Inhibited the growth of tumor cell lines with IC 50 s of 0.2±0.03 nM (for leukemia CCRF-CEM cell line), 0.6±0.1 nM (for ovarian 1A9 cell line), 1.1±0.5 and 6.8±6.1 nM ( for NSCLC A549 and NCI-H1299 cell lines), 1.8±0.6, 7.3±2.3 nM (for breast MX-1W, MCF-7 cell lines), 0.7±0.2, 1.1±0.4, 1.5±0.6, 1.8±0.6, 3.6±0.8, 3.7±2.0, 4.2±2.5, and 5.3±4.1 nM ( for colon HCT-116, DLD-1, Colo205, KM20, SW620, S1, HCT-15, and Moser cell lines), 1.1±0.8, 1.4±0.6 and 1.7±0.5 nM (for melanoma A375, Lox and SK-Mel-2 cell lines). |
In Vivo
Taltobulin (HTI-286; 1.6 mg/kg i.v.) inhibits the growth of human tumor xenografts (e.g., HCT-15, DLD-1, MX-1W, and KB-8-5) in athymic nu/nu female mice
[1]
.
Taltobulin (HTI-286; 3 mg/kg; p.o. gavage) inhibits growth by 97.3 % and 82% in athymic nu/nu female mice with Lox melanoma xenografts and KB-3-1 epidermoid xenograft model, respectively
[1]
.

| Animal Model: | Athymic nu/nu female mice with Lox melanoma model (5-6 weeks of age) [1] |
| Dosage: | 1.6 mg/kg |
| Administration: | Administered i.v.;for 35 days |
| Result: |
Growth of Lox tumors was inhibited by 96-98% on day 12 compared with vehicle-treated controls.
Growth of KB-8-5 tumors was inhibited by 84% on day 14 compared with vehicle-treated controls. Growth of MX-1W tumors was inhibited by 97% compared with vehicle-treated controls. Growth of DLD-1 and HCT-15 tumors was inhibited by 80 and 66%, respectively. |
