AI Article Synopsis
- Casein kinases 1 (CK1) are important signaling molecules and promising targets for treating blood cancers.
- Researchers have discovered a new class of strong and selective inhibitors for CK1 isoforms (CK1α, δ, and ϵ), specifically MU1250, MU1500, and MU1742.
- These inhibitors allow for targeted treatment in cells and include MU1742 as the first potent inhibitor of CK1α, while also showcasing a pharmacophore that can inhibit other key protein kinases.
Article Abstract
Casein kinases 1 (CK1) are key signaling molecules that have emerged recently as attractive therapeutic targets in particular for the treatment of hematological malignancies. Herein, we report the identification of a new class of potent and highly selective inhibitors of CK1α, δ and ϵ. Based on their optimal in vitro and in vivo profiles and their exclusive selectivity, MU1250, MU1500 and MU1742 were selected as quality chemical probes for those CK1 isoforms. At proper concentrations, MU1250 and MU1500 allow for specific targeting of CK1δ or dual inhibition of CK1δ/ϵ in cells. The compound MU1742 also efficiently inhibits CK1α and, to our knowledge, represents the first potent and highly selective inhibitor of this enzyme. In addition, we demonstrate that the central 1H-pyrrolo[2,3-b]pyridine-imidazole pharmacophore can be used as the basis of highly selective inhibitors of other therapeutically relevant protein kinases, e.g. p38α, as exemplified by the compound MU1299.

Selective inhibition of histone deacetylase 8 (HDAC8) has emerged as a promising approach for treating various diseases, including cancer. However, finding key structural features for HDAC8 inhibition and developing effective and selective HDAC8 inhibitors (HDAC8s) pose significant challenges. In the past few years, the development of various scaffolds for inhibiting HDAC8 has significantly risen and the quest continues.

A series of 2,4-disubstituted pyrimidine derivatives bearing 5-substituted-1,3,4 thidiazole were devised and synthesized based on the binding mode of the approved drug Osimertinib with the ATP competitive site of EGFR-L858R/T790M in order to increase selectivity towards double mutant EGFR and potent antitumor activity. Their cellular bioactivity and corresponding enzyme inhibition were studied, and it was revealed that several compounds had significant biological activity and selectivity when compared to the control compounds. One of the most promising compound 8, substantially suppressed the proliferation of H1975 cells and showed significant inhibition of double mutant EGFR-L858R/T790M TK with IC values of 0.

Introduction: Epilepsy remains a challenge, with one-third of patients experiencing refractory seizures despite current anti-seizure medications. The nitrergic system, which involves nitric oxide (NO) and NO synthase (NOS) enzymes, plays a complex role in seizure pathophysiology. Pentoxifylline (PTPh), an FDA-approved phosphodiesterase inhibitor, has anticonvulsant effects; however, its relationship with the pathway is unclear.

The widespread use of antivirals in immunocompromised individuals has led to frequent occurrences of drug-resistant herpes simplex virus 1 (HSV-1) infections. Current antivirals target the viral DNA polymerase (DP), resulting in cross-resistance patterns that emphasize the need for novel treatment strategies. In this study, we assessed whether combining antivirals with different targets affects drug resistance emergence by passaging wild-type HSV-1 under increasing concentrations of acyclovir (ACV), foscarnet (phosphonoformic acid, PFA), or the helicase-primase inhibitor pritelivir (PTV), individually or in combination (ACV + PTV or PFA + PTV).
