Technical Field

The invention belongs to the field of medicines, relates to a new application of a SIRT1 inhibitor nicotinamide, and particularly relates to an application of nicotinamide in preparation of a preparation for treating hand-foot skin reactions.

Background

The concept that tumor growth is dependent on angiogenesis began in the early 70's of the 20 th century, angiogenesis has a significant impact on tumor growth, invasion and metastasis, and anti-angiogenesis has become one of the important strategies for anti-tumor. Vascular Endothelial Growth Factor Receptors (VEGFR) play a crucial role in angiogenesis. The VEGFR small-molecule kinase inhibitor is a kinase inhibitor aiming at VEGFR family, and can remarkably improve the progression-free survival time of tumor patients. However, the toxic and side effect of hand-foot skin reaction (HFSR) is generated in the using process of various VEGFR small-molecule kinase inhibitors, the clinical characteristics are represented by excessive keratinization, and the incidence rate is as high as 40% -60%. This side effect seriously affects the quality of life of the patient and may also lead to down-regulation of the dosage or interruption of the treatment, ultimately threatening the life of the patient.

Because the molecular mechanism of the VEGFR small-molecule kinase inhibitor for inducing HFSR is unknown, no effective strategy for solving the toxic and side effects exists in the clinic at present. For mild HFSR patients can be relieved with keratolytic agents or lubricants, while for patients with moderate or severe HFSR during administration, the dosage of the drug needs to be reduced or even the treatment interrupted. The above methods provide only very limited relief from these symptoms and do not achieve the desired goals of reducing or curing HFSR. Therefore, there is a great need to find a common molecular mechanism for VEGFR small molecule kinase inhibitors to induce HFSR and to find a suitable intervention strategy based on this mechanism.

Niacinamide is a member of the vitamin B family and is a common SIRT1 inhibitor. Nicotinamide is mainly used for preventing and treating pellagra, stomatitis, glossitis and the like in clinic, and can also be used for treating coronary heart disease, viral myocarditis, rheumatic heart disease and the like, but no report of using nicotinamide as HFSR for treating is available.

Disclosure of Invention

The invention aims to provide application of nicotinamide in preparation of a preparation for treating hand-foot skin reaction, wherein the chemical name of the nicotinamide is 3-pyridinecarboxamide, and the molecular formula of the nicotinamide is C₆H₆N₂O, molecular weight 122.13. The hand-foot skin reaction is induced by a VEGFR small molecular kinase inhibitor.

The research of in vivo experiments of animals proves that the SIRT1 inhibitor nicotinamide can be used for treating HFSR induced by the VEGFR small-molecule kinase inhibitor, thereby expanding the clinical application of the VEGFR small-molecule kinase inhibitor. The SIRT1 inhibitor nicotinamide is applied to achieve the purpose of relieving HFSR induced by three VEGFR small molecule kinase inhibitors (regorafenib, apratinib).

The invention has the significance of providing an effective intervention strategy aiming at the HFSR triggered by the VEGFR small-molecule kinase inhibitor. In a mouse HFSR model induced by a VEGFR small-molecule kinase inhibitor, nicotinamide is given to a mouse in a gastric perfusion mode, so that the condition of thickening of the horny layer of the mouse can be obviously improved. The research of in vivo experiments of animals proves that the SIRT1 inhibitor nicotinamide has obvious protection effect on HFSR caused by the VEGFR small molecular kinase inhibitor, thereby improving the safety of clinical use of the VEGFR small molecular kinase inhibitor and simultaneously providing a brand new strategy for treating the HFSR.

The invention has the advantages that: (1) the medicine can effectively treat HFSR induced by the VEGFR small-molecule kinase inhibitor, relieve the hand-foot skin reaction of tumor patients caused by the use of the VEGFR small-molecule kinase inhibitor, and greatly expand the clinical use of the VEGFR small-molecule kinase inhibitor; (2) the nicotinamide has small toxic and side effects and moderate price, can be prepared into proper dosage forms according to requirements, and has high clinical feasibility.
