Androgen receptor antagonist 1 is an orally available full androgen receptor antagonist (IC50: 59 nM). It can be used in the synthesis of PROTAC AR degraders, which results in 24% and 47 % AR protein degradation in LNCaP cells at 1 μM and 10 μM, respectively.
Leelamine hydrochloride, a tricyclic diterpene extracted from pine tree bark, inhibits the transcriptional activity of the androgen receptor, known to regulate fatty acid synthesis [2,3]. This compound acts as a cannabinoid receptor type 1 (CB1) agonist and suppresses SREBP1-regulated fatty acid lipid synthesis in prostate cancer cells, irrespective of androgen receptor status.
ARCC-4 is an enzalutamide-based von Hippel-Lindau (VHL)-recruiting AR PROTAC and outperforms enzalutamide and it is a low-nanomolar androgen receptor (AR) degrader based on PROTAC, with a DC50 of 5 nM. ARCC-4 effectively degrades clinically relevant AR mutants associated with antiandrogen therapy[1].
Boc-Pip-alkyne-Ph-COOH, a PROTAC linker characterized by its alkyl ether composition, plays a crucial role in synthesizing PROTACs including ARD-266. This compound demonstrates significant efficacy in promoting the degradation of androgen receptor (AR) protein across AR-positive prostate cancer cell lines such as LNCaP, VCaP, and 22Rv1, showcasing DC50 values ranging from 0.2-1 nM[1].
VHL Ligand-Linker Conjugates 17 are chemical compounds that consist of a VHL ligand specialized for the E3 ubiquitin ligase, as well as a PROTAC linker. These conjugates are utilized in the synthesis of various PROTACs, including the notable ARD-266. ARD-266 is an exceptionally effective androgen receptor (AR) PROTAC degrader[1].
YT 6-2 analog-1 (compound 2-3) 是一种靶向p62 SQSTM1的自噬靶向配体 (ATL),用于合成AR (Androgen Receptor)的AUTOTAC降解剂ATC-324。ATC-324 通过诱导 AR p62 复合物的形成,促进 AR 的自噬-溶酶体降解,并能降低核 AR 含量,抑制 AR 和 AR-v7 相关基因的表达,对前列腺癌中常见的 AR 突变体也具有降解作用。
