Electronic effect-dependent intramolecular non-covalent interactions on the activity of 4,4-dimethylimidazolidin-2-one pharmacophore-based androgen receptor antagonists.

Because androgen receptor (AR) signalling is important for the development and progression of prostate cancer (PC), AR antagonists are utilized in clinical practices to treat PC and are referred to as androgen deprivation therapy (ADT). However, continued administration of AR antagonists often results in the development of resistance, known as castration-resistant prostate cancer (CRPC). Despite castration, it has been demonstrated that AR signalling continues to be fundamental to tumour growth.

A novel in-cell ELISA method for screening of compounds inhibiting TRKA phosphorylation, using KM12 cell line harboring TRKA rearrangement.

Tropomyosin-related kinase A (TRKA) fusion was originally detected in colorectal carcinoma that had resulted in expression of the oncogenic chimeric protein TPM3-TRKA. Lately, many more rearrangements in TRK family of kinases generating oncogenic fusion proteins have been identified. These genetic rearrangements usually result in fusion of cytoplasmic kinase domain of TRK to another gene of interest resulting in constitutive kinase activity.
