Abstract

The objective of this study was to investigate skin whitening effect of Resorcinol dipentyl ether [1,3-di(pentyloxyl)benzene] by in vitro experiments. Resorcinol dipentyl ether was prepared by alkylation of resorcinol with 1-bromopentane. The reaction products were confirmed by NMR, MS and other analytical equipments. In order to evaluate the skin safety of resorcinol dipentyl ether, the cytotoxicity of the cells constituting the skin (keratinocyte, melanocyte, fibroblast) was analyzed and similar cell viability was observed in all cell lines as compared with the control group. Inhibition of extracellular melanin synthesis effect of resorcinol dipentyl ether was approximately 65.75% at $20{\mu}g/mL$ and inhibition of intracellular melanin synthesis effect of resorcinol dipentyl ether was approximately 53.89% at $20{\mu}g/mL$. The real-time PCR and western blot analysis of mRNA expression and protein expression of tyrosinase, TRP-1, and TRP-2 related to melanogenesis revealed that melanin inhibitory effect of resorcinol dipentyl ether was inhibited from the transcription stage respectively. Finally, this study suggested applicability of Resorcinol dipentyl ether [1,3-di(pentyloxyl)benzene] as a whitening functional cosmetic new material.

레조시놀다이펜틸에터(1,3-di(pentyloxyl)benzene)의 피부 미백 효과를 확인하기 위해 in vitro 실험을 통하여 미백 효과를 평가하였다. 레조시놀다이펜틸에터는 resorcinol과 1-bromopentane의 알킬화반응을 통하여 제조하였으며, 반응 결과물을 NMR, MS 등의 분석장비를 통해 확인하였다. 레조시놀다이펜틸에터의 피부 안전성 평가를 위하여, 피부를 구성하는 세포들(keratinocyte, melanocyte, fibroblast)에 대한 독성을 분석한 결과 대조군에 비해서 모든 세포주들에서 유사한 cell viability를 확인하였다. 세포생존에 영향을 미치지 않는 농도인 $20{\mu}g/mL$에서 세포 외 멜라닌 분비 저해능을 측정한 결과 $20{\mu}g/mL$ 농도에서 약 65.75%까지 농도 의존적으로 멜라닌 분비를 억제하는 것을 확인하였으며, 세포 내 멜라닌 생성 억제율을 측정한 결과에서도 약 53.89%를 억제함을 확인하였다. 멜라닌 형성 관련 티로시나제, TRP-1, TRP-2의 mRNA 발현량과 단백질 발현량을 real-time PCR 방법과 western blot으로 측정을 한 결과 레조시놀다이펜틸에터는 멜라닌 억제효과가 전사(transcription)단계부터 억제하는 것을 확인하였다. 최종적으로 본 연구는 레조시놀다이펜틸에터의 미백기능성화장품 신소재로서의 적용가능성을 제시하였다.
