C6 Ceramide (d18:1/6:0)

C6 Ceramide (d18:1/6:0) (CAS No.: 124753-97-5) is a bioactive, short-chain, cell-permeable ceramide belonging to the sphingolipid family, widely utilized as a functional modulator of intracellular signaling pathways in cancer biology and drug discovery research. As an activator of ceramide-mediated signaling, it regulates key processes such as cell proliferation, apoptosis, and cell cycle progression, with mechanistic involvement in the Akt signaling pathway and downstream modulation of microRNA expression, including miR-29b, thereby influencing tumor progression and endothelial cell behavior. Through these mechanisms, C6 Ceramide suppresses cellular proliferation, migration, and angiogenesis, particularly in models of hematological malignancies such as multiple myeloma. It exhibits broad anticancer activity characterized by induction of apoptosis, inhibition of tumor growth, and sensitization of drug-resistant cancer cells to chemotherapeutic agents, supporting its use as an adjuvant in combination therapy studies. In vitro, its biological effects are typically observed in the low micromolar to micromolar concentration range, depending on cell type and experimental conditions. C6 Ceramide is extensively applied in cell-based assays, mechanistic pathway studies, and preclinical models to investigate sphingolipid signaling and to evaluate strategies for enhancing therapeutic efficacy, with dosing regimens varying according to specific experimental designs and research objectives.
