In search for retinoic acid receptor (RAR) selective ligands, a series of 6-substituted 2-naphthoic acid retinoids were synthesized and evaluated in vitro in a transactivation assay and a competition binding assay for all RARs. These derivatives, in general, showed RAR beta,gamma selectivity. Among these naphthoic acids, oxime derivative 12 was identified as a potent RAR gamma-selective retinoid, while olefinic derivative 11 was found to be comparable to retinoic acid and slightly RAR beta,gamma selective. For the bioassays, a general correlation was observed between the binding affinity of the ligand to the receptors and the potency of the compounds in the transactivation assay. The structure-activity relationship of these naphthoic acids will be discussed.

Nuclear receptors (NRs) are ligand-activated transcription factors that regulate gene expression in response to physiological signals, such as hormones and other chemical messengers. These receptors either activate or repress the transcription of target genes, which in turn promotes or suppresses physiological processes governing growth, differentiation, and homeostasis. NRs bind to specific DNA sequences and, in response to ligand binding, either promote or hinder the assembly of the transcriptional machinery, thereby influencing gene expression at the transcriptional level.

The 3D printing of human tissue constructs requires carefully designed bioinks to support the growth and function of cells. Here it is shown that an additional parameter is how drug-releasing microparticles affect the material properties of the scaffold. A microfluidic platform is used to create all-trans retinoic acid (atRA) polycaprolactone (PCL) microparticles with a high encapsulation efficiency (85.

Acute promyelocytic leukemia (APL) is driven by the specific fusion gene PML-RARA produced by chromosomal translocation. Three classic isoforms, L, V, and S, are found in more than 95% of APL patients. However, atypical PML-RARA isoforms are usually associated with uncertain disease progression and treatment prognosis.

Introduction: Palovarotene is a retinoic acid receptor gamma agonist that was studied in phase-2 and phase-3 clinical trials for the inhibition of new heterotopic ossification (HO) in fibrodysplasia ossificans progressiva (FOP). Despite numerous setbacks and regulatory delays, palovarotene is now the first approved FOP treatment in the U.S.
