Article Abstract
Specific abrogation of cyclin-dependent kinase 5 (CDK5) activity has been validated as a viable approach for the development of anticancer agents. However, no selective CDK5 inhibitor has been reported to date. Herein, a structure-based screening was employed to identify novel scaffolds from a library of compounds to identify potential CDK5 inhibitors that would be relevant for drug discovery. Hits, representatives of three chemical classes, were identified as inhibitors of CDK5. Structural modification of - resulted in and . Compound is a dual inhibitor of CDK5 and CDK2, whereas preferentially inhibits CDK5. Both leads exhibited anticancer activity against acute myeloid leukemia (AML) cells via a mechanism consistent with targeting cellular CDK5. This study provides an effective strategy for discovery of CDK5 inhibitors as potential antileukemic agents.

Two series of triazolo[1,5-a]pyrimidines were designed and synthesized as antiproliferative agents targeting multi kinase inhibition aiming to increase potency and combat drug resistance. The synthesized compounds were tested for their antiproliferative activity. The triazolopyrimidine derivatives 9b, 9c, 12b and 12c showed promising anticancer activities, in particular, compounds 12b and 12c displayed broad spectrum antiproliferative potential against NCI cancer cell lines with GI mean value of 10.

Alzheimer's disease (AD) is a prevalent neurodegenerative disorder with a pressing need for novel therapeutics. However, current medications only offer symptomatic relief, without tackling the underlying pathology. To explore the bioactive potential of marine-derived fungi, this study focused on C23-3, a strain isolated from the coral in Xuwen County, China, which showed a richer metabolite fingerprint among the three deposited strains.

Aberrant activation of microglia plays a crucial role in neuronal injury after ischemic stroke. Cyclin-dependent kinase 5 (Cdk5) is a serine/threonine-directed kinase that plays a significant role in neuronal damage. We investigated the role of Cdk5 in microglial activation and neuronal ferroptosis in cellular and animal models of hypoxic-ischemic neuronal injury.

Introduction: The dysregulation of cyclin-dependent kinases (CDKs) is a key driver of cancer progression, making them attractive therapeutic targets. In CDK4/6 inhibitor (CDK4/6i)-resistant breast cancer, targeting CDK2 offers a promising approach. CDK2 is frequently hyperactivated due to cyclin E1 overexpression or retinoblastoma protein loss, acting as a mechanism that sustains proliferation despite CDK4/6 inhibition.

Introduction: Parkinson's disease (PD) is a progressive, age-associated neurodegenerative disorder characterized by loss of nigrostriatal dopaminergic neurons, leading to motor and non-motor dysfunctions. Central to PD pathogenesis are dysregulated protein kinases, such as LRRK2, PINK1, GSK-3β, and CDK5, that govern neuroinflammation, autophagy impairment, oxidative stress, mitochondrial dysfunction, and α-synuclein aggregation.
Objective: To critically assess the potential of phytoconstituents as modulators of key protein kinases in PD.
