KTC1101

Customer Review

Based on 1 Customer Validation

KTC1101 is an orally active pan-PI3K inhibitor. KTC1101 can inhibit the PI3K signaling pathway, reduce downstream AKT and mTOR phosphorylation, and reduces the expression of Ki67. The anti-tumor effect of KTC1101 has a dual mechanism of action: directly inhibiting tumor cell growth and dynamically enhancing immune response.

In Vitro

KTC1101 (0.1-50000 nM, 48 h) can dose-dependently induce cell cycle stagnation in G1 phase in all tested cell lines (PC3, TMD8, HSC2, HSC4, and CAL33 cells). KTC1101 has anti-proliferative activity, with the IC₅₀ ranging from 20 nM to 130 nM, but has no significant promotion of apoptosis^[1].
KTC1101 (0.1-1000 nM, 1 h) exhibits significant inhibitory activity against all PI3K isoforms in the Adapta kinase assay. The IC₅₀ values of KTC1101 for PI3Kα, PI3Kβ, PI3Kδ and PI3Kγ are 3.72 nM, 36.29 nM, 1.22 nM and 17.09 nM respectively^[1].
KTC1101 (0-125 nM, 48 h) effectively inhibits the PI3K signaling pathway in WB experiments, reduces the phosphorylation of PI3K downstream effectors AKT and mTOR^[1].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 5 mg/mL (10.49 mM); Clear solution

This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
