Living organisms have developed finely regulated homeostatic networks to mitigate the effects of environmental fluctuations in transition metal micronutrients, including iron, zinc, and copper. In Saccharomyces cerevisiae, the tandem zinc-finger protein Cth2 post-transcriptionally regulates gene expression under conditions of iron deficiency by controlling the levels of mRNAs that code for non-essential ferroproteins. The molecular mechanism involves Cth2 binding to AU-rich elements present in the 3' untranslated region of target mRNAs, negatively affecting their stability and translation.

In our search for new and selective mGluR negative allosteric modulators (NAMs), series of 6,7-dihydropyrazolo[1,5-]pyrazin-4(5)-one derivatives were identified from our published series of 1,3,5-trisubstituted pyrazoles. SAR evolution of the initial hit resulted in 100-fold improvement in the mGluR NAM potency and subsequent selection of compound based on its overall profile, including selectivity and ADMET properties.

CML results from a chromosomal translocation, forming the BCR-ABL1 fusion gene. Asciminib has been recently approved for 3rd-line refractory or intolerant patients.
