Description
技术领域
本发明涉及包含RIP激酶(RIPK)抑制剂的用于防脱发或促生发的组合物,更详细地,涉及包含选自由低分子化合物、小干扰核糖核酸(siRNA)、短发夹核糖核酸(shRNA)或抗体组成的组中的一种以上的RIP激酶抑制剂的用于防脱发或促生发的组合物。
背景技术
近来,随着对美容的关注提高,对脱发症的治疗的关注也随之日益高涨。所谓脱发症,是指正常应生长毛发的部位处于没有毛发的状态。毛发虽不涉及与生命直接相关的重要的生理功能,但从美容的观点来看,其作用非常大,此外,还与阻隔紫外光、保护头部等功能相关。若脱发严重,则会在社会生活方面出现问题,也会给心理上带来很大的影响,因此在生活质量方面非常重要。
脱发在临床上可以分为伴有伤痕的瘢痕性脱发与只脱发的非瘢痕性脱发。在瘢痕性脱发的情况下,毛囊被破坏而不再生发。毛发在称为毛囊的部位生成,各毛囊经过周期性地活动和静止的阶段。这种毛发周期的时间间隔取决于身体的不同部位,头发经过2年~6年左右的生长期(anagen)和2周~4周的退行期(catagen)后进入3个月~4个月左右的休止期(telogen)。各毛囊在人的一生具有10次~20次的毛囊生长周期(hair follicle growthcycle)。
现在,作为脱发治疗法最为常用的手术方法为自体毛发移植,广泛实施使用保法止及米诺地尔的药物治疗。在药物治疗的情况下,虽在给药的当时表现出生发的功效,但一旦中断治疗,则再次出现脱发,尤其,米诺地尔的情况下,具有性功能障碍等副作用。
另一方面,RIP激酶(RIP kinase;受体相互作用蛋白激酶(receptor-interactingprotein kinase),RIPK)为与先天免疫信号传递相关的TKL系列丝氨酸/苏氨酸蛋白激酶,在人类中存在RIPK1、RIPK2、RIPK3、RIPK4及RIPK5等5种RIP激酶。RIP激酶抑制剂主要为坏死抑制(韩国授权专利第10-1640068号)或者自身免疫治疗(韩国授权专利第10-1858346号)而研究,上述RIP激酶抑制剂与毛发生长相关的内容尚未公知。
尤其,已知为阻断RIP1/RIPK1途径的necrostatin-1及其衍生物(necrostatin-1s等)、西比利林(sibiriline)、GSK963或GSK2982772为对细胞坏死的基于色氨酸的小分子抑制剂,已知特异性地抑制坏死性凋亡(necroptosis),但有关它们促进毛发生长的效果尚处于未公知的状态。
于是,在本发明中,为了开发更为有效的用于预防及治疗脱发的组合物而努力的结果,确认到选自由低分子化合物、小干扰核糖核酸、短发夹核糖核酸或抗体组成的组中的一种以上的RIP激酶抑制剂不仅促进诱导毛发生长,还在小鼠中确认到显著增加生发的效果,从而完成本发明。

优选地,上述小干扰核糖核酸的特征在于抑制RIPK1或RIPK3基因的表达,但不限定于此,也可以抑制除RIPK1或RIPK3以外的其他RIP激酶相关基因的表达。
上述“抗体”可以与RIP激酶特异性结合来抑制RIP激酶活性,上述抗体不仅可以为具有2个全长的轻链及2个全长的重链的完全形态,还可以使用抗体分子的片段。抗体分子的片段是指保有肽标签(表位,epitope)结合功能的片段,包括单链Fv(scFv)、Fab、F(ab')、F(ab')2及单结构域(single domain)等。
本发明的组合物可以制备为药物组合物、准药品组合物或化妆品组合物。
