Camptothecin Induces PD-L1 and Immunomodulatory Cytokines in Colon Cancer Cells

Medicines, 2019
Background: Immunotherapy has changed the options for the treatment of various cancer types, but not colon cancer. Current checkpoint blockade approaches are ineffective in a large proportion of colon cancer cases, necessitating studies to elucidate its ...

Cell‐Specific Expression and Cellular Compartmental Regulation in Camptothecin Biosynthesis

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant secondary metabolites such as monoterpenoid indole alkaloids (MIAs) show tightly regulated biosynthesis and accumulation in specific organelles of distinct cell types. However, the cell‐specific expression patterns of anticancer MIA camptothecin biosynthetic genes in Ophiorrhiza pumila and the regulatory mechanisms of camptothecin ...

RAD51 and RAD51 paralog inhibition sensitizes nonreplicating quiescent keratinocytes to UV radiation

Photochemistry and Photobiology, EarlyView.
UV radiation and other compounds generate DNA adducts that block transcription and induce cell death if not removed by the nucleotide excision repair system. In this work, we used a small‐scale pharmacological screen to discover that inhibition of the recombinase RAD51 sensitized nonreplicating quiescent keratinocytes to both UVR and other agents that ...

Cytotoxic Effects of Fascaplysin against Small Cell Lung Cancer Cell Lines

Marine Drugs, 2014
Fascaplysin, the natural product of a marine sponge, exhibits anticancer activity against a broad range of tumor cells, presumably through interaction with DNA, and/or as a highly selective cyclin-dependent kinase 4 (CDK4) inhibitor.

Avian Eggshell Evolutionary Adaptations Inform Biomimetic Strategies for Next‑Generation Precision Cancer Theranostics

Advanced Oncology, Volume 1, Issue 1, December 2026.
ABSTRACT The avian eggshell is a sophisticated, multi‐functional biocomposite and, more importantly, an autonomous life‐support system evolved to safeguard embryonic development across dynamic and hostile environments. Discussing eggshell‐inspired biomaterials beyond simple structural imitation, this review translates these evolutionary survival ...

Synthesis and Antiproliferative Activities of Conjugates of Paclitaxel and Camptothecin with a Cyclic Cell-Penetrating Peptide

Molecules, 2019
Cell-penetrating peptide [WR]5 has been previously shown to be an efficient molecular transporter for various hydrophilic and hydrophobic molecules. The peptide was synthesized using Fmoc/tBu solid-phase chemistry, and one arginine was replaced with one ...

Payload‐Based Clinical Pharmacology Review of Approved Antibody–Drug Conjugates: Commonalities and Considerations for Streamlined Development

Clinical Pharmacology &Therapeutics, Volume 120, Issue 3, Page 614-638, September 2026.
Antibody–drug conjugates (ADCs) combine the specificity of an antibody with the potency of a cytotoxic drug. Thirteen ADCs, utilizing seven unique cytotoxic payloads and targeting 11 distinct antigens, are currently approved by the US Food and Drug Administration as of June 2025, representing a rapidly growing and highly promising class of anticancer ...

Cyclins and Cyclin‐Dependent Kinases: Structure, Biological Functions, and Innovative Targeting Strategies in Cancer

MedComm, Volume 7, Issue 9, September 2026.
This work synthesizes recent insights into the pathological roles of cyclins and cyclin‐dependent kinases (CDKs) across human cancers, highlights state‐of‐the‐art innovative approaches (especially targeted degradation and redistribution of CDK/cyclin proteins) for cancer therapy, and outlines future directions for CDK/cyclin‐related biomedical research.
