Targeting BCL-XL via PROTACs is a promising strategy in reducing BCL-XL inhibition associated platelet toxicity. Recently, we reported potent BCL-XL PROTAC degraders that recruit VHL or CRBN E3 ligase. However, low protein expression or mutation of the responsible E3 ligase has been known to result in decreased protein degradation efficiency of the corresponding PROTACs. To overcome these mechanisms of resistance, PROTACs based on recruiting alternative E3 ligases could be generated. Thus, we designed and synthesized a series of PROTACs that recruit IAP E3 ligases for BCL-XL degradation Among those PROTACs, compound 8a(I) efficiently degrades BCL-XL in malignant T-cell lymphoma cell line MyLa 1929 while CRBN-based PROTACs that have high potency in other cancer cell lines show compromised potency, likely due to the low CRBN expression. Moreover, compared with the parent compound ABT-263, PROTAC 8a shows comparable cell killing effects in MyLa 1929 cells whereas the on-target platelet toxicity is significantly reduced. Our findings expand the anti-tumor spectra of BCL-XL degraders and further highlight the importance of selecting suitable E3 members to achieve effective cellular activity.
4897-84-1, Methyl 4-bromobutyrate,also as known as 4-Bromobutyric acid methyl ester, is a useful research compound. Its molecular formula is C5H9BrO2 and its molecular weight is 181.03 g/mol. The purity is usually 95%.
4-Bromobutyric acid methyl ester is a synthetic compound that can be used to inhibit the activity of the G1 phase cyclin-dependent kinases. It has been shown to inhibit protein synthesis by alkylating the amino groups of proteins and fatty acids. 4-Bromobutyric acid methyl ester also inhibits the growth of cancer cell lines, such as renal carcinoma cells. The mechanism of action for this drug is not well understood, but it may be due to its ability to bind with monoclonal antibodies and enter kidney cells by passive diffusion., Formula: C5H9BrO2
