Special Issue Information

Dear Colleagues,

The exploration of natural products and their derivatives has long served as a foundation in the discovery of novel anticancer agents. Nature offers a vast chemical diversity, providing compounds with unique structures and potent bioactivities. This Special Issue, entitled “Advances in Anticancer Activity of Natural Products and Related Compounds”, seeks to highlight the recent advances in the identification, characterization, and application of natural compounds in cancer research. We welcome the submission of original research articles and reviews that bring about novel insights into the molecular mechanisms of action, structure–activity relationships, and innovative delivery systems of these bioactive agents. Studies on the synergistic effects of natural products with conventional therapies, as well as investigations into overcoming drug resistance, are also encouraged. This Special Issue aims to inspire interdisciplinary collaborations and foster the development of natural product-based cancer therapeutics that will ultimately contribute to improvements in patient outcomes.

Dr. Alexandra Mioc
Guest Editor

Claoxylon longifolium (Euphorbiaceae) is an indigenous vegetable that has been used in southern Thai traditional medicine and cuisine. A bioassay-guided approach was adopted to investigate the phytochemicals and chemopreventive potential of C. longifolium leaves and stems. Phytochemical investigation of the active MeOH fractions afforded six known compounds, including caffeic acid (1), isovitexin (2), and vicenins 1–3 (3–5) from leaves and hexadecanoic acid methyl ester (6) from stems. Their structures were determined by spectroscopic means. Ten constituents were tentatively identified from the oily fractions of stems by GC-MS. Non-cytotoxic concentrations of compounds 16 were identified using the MTT cell viability assay. The ability of compounds 16 at non-cytotoxic concentrations to induce Nrf2 activation, correlating to their potential chemopreventive properties, was determined using a luciferase reporter assay in the AREc32 cell line. Only vicenin 1 (3) was considered to be a potent chemopreventive compound, as it increased luciferase activity by 2.3-fold. In silico studies on compounds 25 and vitexin (16) revealed the potential of these compounds as cancer chemopreventive and chemotherapeutic agents. This study provides the first report on the chemopreventive properties of C. longifolium. All identified and isolated compounds are reported here for the first time from this species. Full article

The BCR-ABL fusion oncoprotein, a constitutively active tyrosine kinase, plays a central role in the pathogenesis of chronic myeloid leukemia (CML). While tyrosine kinase inhibitors (TKIs) have transformed CML treatment, issues such as drug resistance, particularly involving mutations like T315I, and adverse effects underscore the need for alternative or complementary therapeutic strategies. Natural products derived from plants have long served as a reservoir for anticancer agents, offering structural diversity and multi-targeted bioactivity. Notably, many plant-based compounds exhibit anticancer effects with comparatively lower toxicity and fewer side effects than synthetic TKIs, making them attractive candidates for safer long-term use. This review explores the recent advances in plant-based natural compounds that directly or indirectly inhibit BCR-ABL kinase activity and its downstream signaling pathways. Key compounds are discussed with respect to their mechanisms of action, structure–activity relationships, and potential to overcome TKI resistance. Several of these compounds directly target BCR-ABL or promote its degradation, while others inhibit downstream effectors such as STAT5 and PI3K/Akt, leading to apoptosis and growth inhibition of leukemic cells. The synergistic potential of these natural products with existing TKIs and their promise to target drug-resistant CML cells further highlight their translational value. By integrating insights from molecular pharmacology, medicinal chemistry, and leukemia biology, this review supports the continued investigation of plant-derived agents as novel or adjunctive therapies against BCR-ABL-driven leukemias.
