NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of supplying key compounds for cutting-edge research, and Nicotinamide (CAS 98-92-0) plays a critical role in studies related to DNA repair and cancer therapeutics.

At a cellular level, Nicotinamide is known to impact DNA repair pathways, most notably through its interaction with poly(ADP-ribose) polymerases (PARPs). PARPs are crucial enzymes that detect and signal DNA single-strand breaks, initiating repair cascades. Nicotinamide acts as a competitive inhibitor of PARP activity, modulating the efficiency of these repair processes. This inhibitory effect is of significant interest in oncology.

In cancer research, understanding how cells repair DNA damage is paramount, especially in the context of radiotherapy and chemotherapy, which often aim to induce DNA damage in cancer cells. By inhibiting PARP, Nicotinamide can potentially sensitize cancer cells to DNA-damaging treatments, making these therapies more effective. Studies have explored combinations of Nicotinamide with various cancer treatments to enhance therapeutic outcomes.

Furthermore, Nicotinamide's ability to support cellular energy levels through its role as an NAD+ precursor can also indirectly influence the DNA repair machinery, which is energy-intensive. Research is actively investigating how modulating NAD+ levels with compounds like Nicotinamide can bolster cellular resilience or, conversely, exploit vulnerabilities in cancer cells.

The application of Nicotinamide in chemoprevention, particularly against UV-induced skin damage and subsequent skin cancers, also highlights its protective role concerning DNA integrity. Studies suggest that Nicotinamide can enhance the repair of UV-induced DNA damage in skin cells, thereby reducing the risk of developing certain skin cancers.

NINGBO INNO PHARMCHEM CO.,LTD. provides researchers with high-purity Nicotinamide to facilitate these critical investigations into DNA repair and cancer biology. The compound's complex interactions with cellular mechanisms offer promising avenues for developing novel cancer therapies and protective strategies.
