AZD9496

To test this hypothesis, we treated MCF-7 and T47D ER-positive breast cancer cells with 17-β-estradiol (E2), either alone or in combination with selective ERα antagonist AZD9496, selective ERβ antagonist PHTPP, DNA methyltransferase (DNMT) inhibitor RG108, and selective ER degrader Fulvestrant (Ful). RG108 strengthened UV-C-induced pyroptosis, and Ful reversed the inhibitory effects of E2 on UV-C-induced pyroptosis of MCF-7 and T47D cells. Taken together, our study suggests that E2 down-regulated GSDME expression in ERα-positive breast cancer by promoting GSDME promoter methylation, and inhibited UV-C-induced pyroptosis.

The use of ERα antagonist AZD9496 reduced the effect of E2 on the promotion of M2 polarization in AMs...Interference with Brms1 mRNA production reduced the gene expression of Arg1 and YM1 in AMs undergoing M2 polarization after E2 stimulation. In summary, E2 exacerbates airway inflammation in asthmatic mice and binds to ERα, upregulating Brms1 expression and mediating M2 polarization of AMs.

Pharmacological blockade or siRNA silencing of ERα limited cell survival and metastasis while restoring tight junction protein expression. In conclusion, these findings highlight the potential of ERα as a prognostic marker for CRC and its role in metastasis.

The significant advantage of this method is that the mathematical model does not have to contain a small parameter (as is standard in perturbation theory). However, it is possible to artificially introduce a small parameter into the system of equations, making it possible to study the model using asymptotic methods.

Mechanically, the AZD9496 and fulvestrant significantly blocked JAK2/STAT5B pathway in GT1-1 cells and xenograft mice. Our results provide substantial evidence for the subsequent clinical use of AZD9496 in the treatment of patients with pituitary adenoma.

This study revealed that PBX1 participated in estrogen mediated BCa progression and chemo-resistance through binding and activating estrogen receptors. Hence, PBX1 may serve as a potential prognostic and therapeutic target for BCa treatment.

Whole blood (WB) specimens were collected at serial time points from patients with advanced ER-POS/HER2-negative (NEG) advanced breast cancer in a phase I trial of AZD9496, an oral selective ER degrader (SERD) ET...Intra-patient, inter-CTC genomic heterogeneity was observed, at times between timepoints, in subclonal alterations. Our analysis suggests that serial monitoring of the CTC genome is feasible and should enable real-time tracking of tumor evolution during progression, permitting more combination precision medicine interventions.

Fulvestrant (SERD, #S1191), AZD9496 (novel, orally bioavailable SERD, #S8372) and ribociclib (CDK4/6 inhibitor, #S7440) were obtained from Selleckchem. Using publicly available data, our results highlight the positive impact ET has on HER2+ breast cancer survival outcome. In vitro data supports the combination of novel SERDs and neratinib as a therapeutic strategy that warrants further investigation in HER2+/ER+ breast cancer.

SAR studies revealed that while the acrylic acid moiety of AZD9496 is scaffold hopping into benzoic acid, compound D24 exhibits potent binding affinity with ERα, good degradation efficacy of ERα, and inhibitory effect against the MCF-7 breast cancer cell line. Besides, D24 also displays good antitumor efficacy in the MCF-7 human breast cancer xenograft model in vivo, favorable pharmacokinetic properties, excellent druggability, and good safety property, making D24 as a promising drug candidate of SERD for further evaluation.
