| In Vitro | NVP-CLR457 (compound 40) shows the mTOR activity, with an IC50 of 2474 ± 722 nM, and inhibits RPS6 phosphorylation with an IC50 of 1633 ± 54 nM[1]. NVP-CLR457 has no impact on the DDR response at concentrations of 1 and 5 μM[1]. NVP-CLR457 has no effect on the rate of microtubule polymerization[1]. Western Blot Analysis Cell Line: U87MG cells[1] Concentration: 0, 1. 4, 16, 63, 250, 1000 nM Incubation Time: 24 h Result: Inhibited the readouts of class I PI3K activity in a dose-dependent manner, with IC50 and IC90 values of 100 and 507 nM determined for the inhibition of S473P-Akt, and had no significant change in the readouts of mTOR activity. |
| In Vivo | NVP-CLR457 (compound 40) (athymic nude mice bearing xenotransplanted Rat1-myr-p110α tumors, 3-20 mg/kg, PO, daily for 8 days) shows a dose-dependent inhibition of tumor growth[1]. NVP-CLR457 (Mice bearing xenograft HBRX2524 human primary breast tumor, 40 mg/kg, PO, daily for 15 days) inhibits the tumor growth throughout the study[1]. NVP-CLR457 (male Sprague-Dawley rats, 1.0 mg/kg, IV; 3.0 mg/kg, PO; once) shows high level of oral exposure and bioavailability[1].

Animal Model: Female OF1 mice, male beagle dogs[1] Dosage: 3 mg/kg (IV) and 10 mg/kg (PO) for mice, 0.1 mg/kg (IV), 0.3 mg/kg (PO) for dogs Administration: IV or PO, once (Pharmacokinetic Analysis) Result: Showed low clearance, moderate volume of distribution, and rapid absorption leading to moderate to long half-lives and high oral bioavailability. Animal Model: Male Sprague Dawley rats, male beagle dogs[1] Dosage: 0.3, 3, 30, 100 mg/kg Administration: PO, once (Pharmacokinetic Analysis) Result: Led to under-proportional increases in exposure (both AUC and Cmax) and much longer Tmax values when it formulated as a suspension of the crystalline material. Animal Model: Female athymic nude mice (bearing xenotransplanted Rat1-myr-p110α tumors)[1] Dosage: 3, 10, and 20 mg/kg Administration: PO, daily for 8 days Result: Observed dose-dependent exposure and PD responses, and showed a dose-dependent inhibition of tumor growth. The 3 mg/kg dose achieved 80% S473P-Akt inhibition only at the 1 h time point; the 10 mg/kg dose at the 1 and 4 h time points; and the 20 mg/kg at the 1, 4, and 10 h time points, with a high level of inhibition remaining at the 14 h time point (76%). Animal Model: Mice bearing xenograft HBRX2524 human primary breast tumor[1]Dosage: 40 mg/kg Dosage: 40 mg/kg Administration: PO, daily for 15 days Result: Inhibited the tumor growth throughout the study, and showed a significant level of regression the end of the 15 day treatment period. |
