at-6

AT6 is a PROTAC AT1 analog which is a highly selective bromodomain (Brd4) degrader.

YT 6-2 is an autophagy-targeting ligand (ATL) aimed at p62/SQSTM1, used in the synthesis of AUTOTAC degrader ATC-324. ATC-324 induces the formation of AR/p62 complexes, leading to the autophagic-lysosomal degradation of AR. It reduces nuclear AR levels, downregulates the expression of AR and AR-v7 target genes, and also degrades common AR mutants in PCa.

YT 6-2 analog-1 (compound 2-3) serves as an autophagy-targeting ligand (ATL) aimed at p62/SQSTM1, useful in synthesizing the AUTOTAC degrader ATC-324 for the Androgen Receptor (AR). ATC-324 promotes the formation of AR/p62 complexes, leading to the autophagic-lysosomal degradation of AR. It effectively reduces nuclear AR levels, downregulates the expression of AR and AR-v7 target genes, and can degrade common AR mutants found in prostate cancer (PCa).

Alkyne-PEG6-acid is a bifunctional PEG crosslinker utilized in biological conjugation and as a component in small molecule synthesis. This crosslinker bears a carboxyl group at one end and an alkyne group at the other. In PROTACs, it is known as 2-2-2-2-2-2-6 PROTAC® linker and is also employed in the synthesis of antibody-drug conjugates.

HEMTAC CDK4/6 degrader 1 is a PROTAC connected by ligands for HSP90 and CDK4/6 with a \( K_d \) value of 35.7 μM. It induces CDK4/6 degradation in B16F10 melanoma cells, arrests the cell cycle at the G0/G1 phase, and induces apoptosis. HEMTAC CDK4/6 degrader 1 can be used in cancer research [1].
