Summary: Cyclin-dependent kinases (CDKs) have important roles in normal cells and can be targeted for cancer therapy. CDK4 inhibitors have been approved for advanced breast cancer treatment. However, the development of selective inhibitors for individual CDKs is challenging due to the highly conserved ATP-binding site.

Summary: The introduction of CKI inhibitors has been a major development in the treatment of advanced breast cancer, with potential applications beyond metastatic breast cancer treatment. Evidence suggests that these agents have impacts on cancer immunology and metabolism, expanding our understanding of their therapeutic effects. Challenges and opportunities in the 2020s, including treatment resistance and biomarker development, are anticipated in the continued research and application of CKIs.

Summary: Cyclin-dependent kinase inhibitor drugs can induce neutrophil apoptosis and enhance inflammation resolution. In this study, CDKi showed significant effects on macrophage pro-inflammatory mediator production and viability. Targeting CDK9 inhibited an inflammatory phenotype in human MDMs, suggesting its importance in therapeutically targeting pro-inflammatory macrophage functions during chronic inflammation.

Summary: The study reported a series of baicalein derivatives that significantly inhibited the proliferation of MCF-7 tumor cells and the activity of CDK1/cyclin B kinase. Among them, compound 4a showed better inhibition against MCF-7 proliferation, while compound 3o exhibited the best activity against CDK1/cyclin B kinase. These findings demonstrate that baicalein derivatives can be used as CDK1 inhibitors fighting against cancer.

Summary: Ovarian cancer is a deadly disease that is often diagnosed late, resulting in poor prognosis. Platinum-based therapies are commonly used, but resistance to these treatments is common, making prognosis even worse. This study aimed to evaluate the effectiveness of CDK inhibitors in platinum-resistant ovarian cancer models and their potential clinical utility. The results showed that the CDK inhibitor, dinaciclib, was highly effective in both cell lines and primary cells of ovarian cancer, even more so than cisplatin. Furthermore, resistance to cisplatin did not affect the sensitivity to dinaciclib, and the two drugs had an additive effect when used together. This suggests a potential role for pan-CDK inhibitors in the treatment of advanced and platinum-resistant ovarian cancer.

Summary: This study investigated the functional roles of Giardia lamblia CDKs (GlCDKs) and their cognate cyclins. Using morpholino-mediated knockdown and coimmunoprecipitation, the functions of GlCDK1 and GlCDK2 were distinguished. GlCDK1 with Glcyclin 3977 plays a crucial role in flagellum formation and cell cycle control of G. lamblia, while GlCDK2 with Glcyclin 22394/6584 is involved in cell cycle control.

Summary: This study reveals a new regulatory cross-talk between p27(Kip1) and AhR, as p27(Kip1) interacts with AhR to negatively regulate AhR-mediated transcriptional responses. This adds to the existing knowledge that p27(Kip1) is a direct regulator of AhR transcription, providing a more comprehensive understanding of the regulatory interactions between p27(Kip1) and AhR.

Summary: We report a novel series of 3,5,7-trisubstituted pyrazolo[1,5-a]pyrimidines and their inhibitory activity on FLT3-ITD, CDK2, and CDK9. Compound 10b showed strong inhibition against all kinases and exhibited selectivity towards FLT3-ITD in MOLM13 and MV4-11 cell lines. Further analysis confirmed FLT3 as a cellular target of 10b through biochemical assays and molecular docking.

Summary: Plasmodiophora brassicae is a pathogen that causes clubroot disease in cruciferous plants, leading to morphological changes and symptoms such as gall formation and leaf abscission. The homeostasis of cytokinin and auxin appears to be crucial for club development.

Summary: Targeting cyclin-dependent kinase 7 (CDK7) with a new trisubstituted pyrazolo[4,3-d]pyrimidine derivative, LGR6768, inhibits CDK7 in the nanomolar range and shows favorable selectivity across the CDK family. LGR6768 affects cell cycle regulation and transcription by inhibiting the phosphorylation of cell cycle CDKs and the carboxy-terminal domain of RNA polymerase II. It limits leukemia cell proliferation and induces apoptosis through changes in protein and mRNA levels related to CDK7 inhibition.

Summary: Small molecule Bruton's tyrosine kinase (BTK) inhibitors, including ibrutinib, have shown potential as effective treatments for haemato-oncological diseases. Recent studies have identified HER2 as an off-target kinase of BTK inhibitors, suggesting that these drugs may be repurposed for HER2-positive breast cancer. In this study, we investigated the anticancer effects of zanubrutinib, evobrutinib, tirabrutinib and acalabrutinib in different BCa cell lines and found that zanubrutinib effectively inhibits the HER2 signalling pathway and reduces cell proliferation. These findings support the potential use of zanubrutinib in HER2-amplified solid tumours.

Summary: Increasing crop productivity and mitigating yield losses under stressful conditions are major challenges in agriculture. A recently discovered compound, MTU, delays senescence and enhances the growth of wheat plants. Multiyear field trials demonstrate that treatment with MTU increases average grain yields of wheat and barley by 5-8%. This compound acts independently of cytokinins or other phytohormones and appears to be the only chemical known to affect the stability and activity of PSI.

Summary: This research presents a highly sensitive method for the reliable determination of seven OPDA-aa compounds in plants. The method was optimized for extraction, sample clean-up, and final analysis. Five endogenous (+)-OPDA-aa were identified and their levels were estimated in mechanically wounded Arabidopsis thaliana leaves, with a peak observed 60 minutes after the wounding. The synthetic and analytical methodologies developed in this study will contribute to the understanding of the biological significance of these metabolites in plants.

Summary: B-Box-containing zinc finger transcription factor BBX21 inhibits hypocotyl elongation in Arabidopsis through the brassinosteroid pathway. It reduces sensitivity to synthetic active brassinosteroid 24-epiBL at low concentrations in simulated shade and represses the biosynthesis and signaling genes of brassinosteroids. BBX21 integrates brassinosteroid homeostasis and shade-light signaling to fine-tune hypocotyl elongation in Arabidopsis.

Summary: Antibiotic resistance is a major threat to public health, with Gram-negative bacteria presenting unique challenges due to their low permeability and efflux pumps. Limited understanding of the chemical rules for overcoming these barriers hinders antibacterial drug discovery. Efforts to address this issue, such as screening compound libraries and using cheminformatic analysis, have led to the design of sulfamidoadenosines with diverse substituents, showing potential utility in accumulation in Escherichia coli.
