Embodiment Construction

[0033] The technical solutions of the present invention will be further described below in conjunction with the drawings and embodiments.

[0034] After research, we found that the changes in gene expression after noise exposure were mainly enriched in the "cell cycle signaling pathway". Through qPCR verification, we found that the expression of CDK1 and Cyclin B were up-regulated after noise exposure. Therefore, it was inferred that noise-induced hearing loss is related to the activation of CDK1.

[0035] Riviciclib hydrochloride (p276-00) is a CDK1, 4, 9 inhibitor, so the present invention provides a new application of Riviciclib hydrochloride (p276-00), that is, Riviciclib hydrochloride (p276-00) is used in the preparation and prevention of noise-induced hearing loss Loss of drug use.

[0036] Riviciclib hydrochloride (p276-00) of the present invention can be used alone when preparing the medicine for preventing and treating noise-induced hearing loss; it can also be used ...

Abstract

The invention discloses the application of Riviciclib hydrochloride (p276-00) in the preparation of medicines for preventing and treating noise-induced hearing loss, relates to the field of medicine, and is used to solve the problem of scarcity of existing medicines for preventing and treating noise-induced hearing loss. By using the animal model experiment method of noise-induced hearing loss to detect the hearing and inner hair cell function of mice after noise exposure, it was found that Riviciclib hydrochloride (p276‑00) has a good effect on the number and function of inner hair cell synapses when noise is exposed. The protective effect of Riviciclib hydrochloride (p276‑00) has been visually verified to prevent and treat noise-induced hearing loss. It can be used to prepare drugs for preventing and treating noise-induced hearing loss, and has good research and application prospects.

Description

technical field [0001] The invention relates to the field of medicine, in particular to the new application of Riviciclib hydrochloride (p276-00), and more specifically, to the application of Riviciclib hydrochloride (p276-00) in the preparation of medicines for preventing and treating noise-induced hearing loss. Background technique [0002] Noise-induced deafness is one of the most common acquired sensorineural hearing loss. At present, more than 12% of the world's population is at risk of noise-induced hearing loss. As exposure to traffic noise and entertainment noise becomes more and more common in daily life, the ribbon synapse damage between the inner hair cells and the afferent nerve often has an insidious onset after noise exposure, which will not only accelerate the occurrence of presbycusis, but also Increased risk of dementia has become a serious potential health threat, resulting in serious social problems and economic burden. The damage of inner hair cell ribbo...
