NCP07

NCP07 is a PROTAC degrader targeting the coactivator-binding site (CBS) of ERα. NCP07 induces the formation of the ERα-NCP07-VHL ternary complex and promotes ERα degradation via the ubiquitin-proteasome system. NCP07 induces apoptosis and cell cycle arrest in endocrine therapy-resistant breast cancer cells. NCP07 inhibits the proliferation of wild-type and ESR1-mutant breast cancer cells. NCP07 is applicable to breast cancer-related research.

Anti-cancer

NCP07 potently inhibits the proliferation of wild-type MCF-7 breast cancer cells with an IC₅₀ of 0.25 μM; it potently inhibits the proliferation of endocrine-resistant LCC2 breast cancer cells with an IC₅₀ of 1.01 μM; and it potently inhibits the proliferation of ESR1-mutant MCF-7^EGFR, MCF-7^D538G and MCF-7^Y537S breast cancer cells, with IC₅₀ values ranging from 0.13 to 1.22 μM^[1].
NCP07 (5-10 μM; 24 h) selectively degrades ERα in wild-type MCF-7 breast cancer cells^[1].
NCP07 (1-10 μM; 24 h) selectively degrades ERα in endocrine-resistant LCC2 breast cancer cells in a concentration-dependent manner^[1].
NCP07 (1-10 μM; 12 h) selectively degrades ERα in a concentration-dependent manner in T47D breast cancer cells as well as ESR1-mutated MCF-7^EGFR, MCF-7^D538G and MCF-7^Y537S breast cancer cells^[1].
NCP07 (5 μM) induces ERα degradation in endocrine-resistant LCC2 breast cancer cells via specific binding to the ERα coactivator binding site (CBS); it can induce the formation of a stable ERα-NCP07-VHL ternary complex in endocrine therapy-resistant LCC2 breast cancer cells through specific binding to ERα CBS^[1].

Anti-cancer

Apoptosis

NCP07 (0.1-20 μM; 72 h) induces apoptosis in endocrine-resistant LCC2 breast cancer cells in a concentration-dependent manner^[1].
NCP07 (1-10 μM; 72 h) activates the apoptotic signaling pathway in endocrine-resistant LCC2 breast cancer cells, inducing caspase-3 activation and PARP cleavage^[1].

Anti-cancer

Cell Cycle Regulation

NCP07 (1-20 μM; 48 h) selectively induces G1-phase cell cycle arrest in endocrine-resistant LCC2 breast cancer cells in vitro in a concentration-dependent manner^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis^[1]

Cell Line:

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.
