Description

오론 화합물을 포함하는 미백용 화장료 조성물{Cosmetic composition for whitening comprising aurone compound}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cosmetic composition for whitening comprising an aurone compound,

본 발명은 오론 화합물을 포함하는 미백용 화장료 조성물에 관한 것으로, 더욱 상세하게는 특정 구조의 오론 화합물을 포함하는 미백용 화장료 조성물에 관한 것이다.The present invention relates to a whitening cosmetic composition comprising an ool compound, and more particularly to a whitening cosmetic composition containing an ool compound having a specific structure.

오론(aurone)은 천연물에 많이 존재하는 화합물로서, 꽃 및 과일 등에서 노란색을 나타내는 색소 기능을 한다. 오론은 다양한 생리활성을 나타냄에도 불구하고 이에 대한 연구가 시작된지는 그리 오래되지 않았다. 오론 유도체 중에서 설퍼레틴(sulfuretin)은 항염증 활성을, 오로이시딘(aureusidin)과 브락테아틴(bracteatin)은 항산화 활성을 나타내며, 이 외에 항박테리아, 항진균과 같은 다양한 생리 활성을 나타내는 것으로 보고된 바 있다.Aurone (aurone) is a compound that exists in many natural products and functions as a pigment that shows yellow in flowers and fruits. Although Oron exhibits a variety of physiological activities, it has not been long since the study began. Among the oron derivatives, sulfuretin exhibits anti-inflammatory activity, and aureusidin and bracteatin exhibit antioxidative activity. In addition, they have been reported to exhibit various physiological activities such as antibacterial and antifungal agents have.

한편, 티로시나제는 포유동물, 식물, 균류 등 천연에 존재하고 페놀(phenol) 및 카테콜(catechol) 등의 기질을 수용하는 구리를 포함하는 효소이다. 이 효소는 멜라닌 생합성의 첫 두 단계에 관여하여 L-티로신(L-tyrosine)을 L-DOPA(L-3,4-dihydroxyphenylalanine)로 히드록실화(hydroxylation)시키고, o-퀴논(o-quinone, dopaquinone)으로 산화시키는 역할을 한다. 도파퀴논(Dopaquinone)은 몇 단계의 반응을 통해 멜라닌으로 전환되어 피부 색소침착의 원인 물질로 작용한다. 또한 식품 산업에서 티로시나제는 과일과 채소의 안정성을 제어하는 표적 효소 역할을 한다. 이에 따라 보다 안전하고 효과적인 티로시나제 저해제를 개발하는 것은 식품 및 화장품 산업에서 상당히 중요한 해결과제로 인식되어지고 있다.On the other hand, tyrosinase is an enzyme that exists in nature such as mammals, plants, fungi, and contains copper that accepts substrates such as phenol and catechol. The enzyme is involved in the first two steps of melanin biosynthesis and hydroxylation of L-tyrosine to L-DOPA (L-3,4-dihydroxyphenylalanine), o-quinone, dopaquinone. Dopaquinone is converted to melanin through several steps to act as a cause of skin pigmentation. In the food industry, tyrosinase also acts as a target enzyme to control the stability of fruits and vegetables. Accordingly, the development of safer and more effective tyrosinase inhibitors has been recognized as a significant problem in the food and cosmetic industry.

대한민국 특허공개 제2006-0107374호는 히드록시 치환기를 갖는 오론 화합물을 포함하는 미용 또는 제약학적 탈색케어 조성물을 개시한 바 있다.Korean Patent Laid-Open Publication No. 2006-0107374 discloses a cosmetic or pharmaceutical decolorizing care composition comprising an Oron compound having a hydroxy substituent.

그러나, 현재까지 티로시나제 저해 활성과 관련한 효과적인 미백 효능을 나타내는 오론 화합물은 보고된 바 없으며, 이에 따라 우수한 미백 효능을 갖는 오론 화합물의 개발이 요구된다.However, no Oron compounds have been reported so far that exhibit an effective whitening effect in relation to tyrosinase inhibitory activity, and accordingly, the development of Oron compounds having excellent whitening effect is required.
