Discovery of a C-8 hydroxychromene as a potent degrader of estrogen receptor alpha with improved rat oral exposure over GDC-0927
Bioorg Med Chem Lett 2019 Aug 15;29(16):2090-2093.PMID:31311734DOI:10.1016/j.bmcl.2019.07.013.
Phenolic groups are responsible for the high clearance and low oral bioavailability of the estrogen receptor alpha (ERα) clinical candidate GDC-0927. An exhaustive search for a backup molecule with improved pharmacokinetic (PK) properties identified several metabolically stable analogs, although in general at the expense of the desired potency and degradation efficiency. C-8 hydroxychromene 30 is the first example of a phenol-containing chromene that not only maintained excellent potency but also exhibited 10-fold higher oral exposure in rats. The improved in vivo clearance in rat was hypothesized to be the result of C-8 hydroxy group being sterically protected from glucuronide conjugation. The excellent potency underscores the possibility of replacing the presumed indispensable phenolic group at C-6 or C-7 of the chromene core. Co-crystal structures were obtained to highlight the change in key interactions and rationalize the retained potency.
Maximizing ER-α Degradation Maximizes Activity in a Tamoxifen-Resistant Breast Cancer Model: Identification of GDC-0927
ACS Med Chem Lett 2018 Dec 6;10(1):50-55.PMID:30655946DOI:10.1021/acsmedchemlett.8b00414.
The further optimization of ER-α degradation efficacy of a series of ER modulators by refining side-chain substitution led to efficacious selective estrogen receptor degraders (SERDs). A fluoromethyl azetidine group was found to be preferred and resulted in the identification of bis-phenol chromene 17ha. In a tamoxifen-resistant breast cancer xenograft model, 17ha (ER-α degradation efficacy = 97%) demonstrated tumor regression, together with robust reduction of intratumoral ER-α levels. However, despite superior oral exposure, 5a (ER-α degradation efficacy = 91%) had inferior activity. This result suggests that optimizing ER-α degradation efficacy leads to compounds with robust effects in a model of tamoxifen-resistant breast cancer. Compound 17ha (GDC-0927) was evaluated in clinical trials in women with metastatic estrogen receptor-positive breast cancer.
