TNG961

TNG961 is a selective and orally active CRBN-mediated HBS1L molecular glue degrader. TNG961 induces formation of an HBS1L-TNG961-CRBN ternary complex, leading to potent degradation of HBS1L and secondary destabilization of its binding partner PELO. TNG961 can reduce HBS1L protein levels, thereby disrupting the PELO region involved in ribosome rescue. TNG961 can be used for the study of FOCAD-deficient cancers, such as pancreatic cancer.

Biological Activity

Description

In Vitro

In vitro, TNG961 leads to a dose-dependent decrease in HBS1L protein levels, which in turn destabilizes the portion of PELO involved in ribosome rescue. TNG961 displays proteome-wide selectivity for HBS1L, with no change in SALL4 protein level as determined by western blot. TNG961-induced HBS1L degradation and PELO destabilization can both be rescued by inactivation of CRBN confirming mechanism^[1].
In engineered HiBiT knock-in cells, treatment with TNG961 induces maximal HBS1L degradation within 4 hours, without affecting GSPT1 protein levels^[1].

In Vivo

TNG961 (Oral administration) induces dose-dependent degradation of HBS1L and subsequent destabilization of PELO protein in FOCAD-deleted xenograft models, resulting in tumor stasis or regression across multiple lineages^[1].

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.
