Screening the active ingredients of plants via molecular docking technology and evaluating their ability to reduce skin photoaging.
The active ingredients of plants were screened by molecular docking technology and the result were verified. According to the verification results of molecular docking, the five active ingredients were combined in equal proportions to form a compound drug. In the HaCaT photoaging model, the effects of the compound drug on antioxidant and senescence-associated secretory phenotype (SASP) factors of the NF-κB and MAPK pathways were studied via SOD and MDA kits, DCFH-DA fluorescent probes and ELISA. In the skin photoaging model, the effects of the compound drug on antioxidants and the SASP factors of the NF-κB and MAPK pathways were studied via SOD, MDA, and CAT kits and ELISA. The results revealed that the compound drug increased SOD activity, decreased the MDA content and intracellular ROS, inhibited IL-6 in the NF-κB pathway, and inhibited MMP-1 and collagen I in the MAPK pathway. The results of HE, Masson and Victoria blue skin staining revealed that the compound drug inhibited abnormal thickening of the epidermis, abnormal breaking and accumulation of collagen fibers and elastic fibers, and maintained their orderly arrangement. Moreover, the results revealed that the compound drug increased SOD, CAT and collagen I, and reduced the MDA content, the SASP factors IL-6 and TNF-α of the NF-κB pathway, and the SASP factors MMP-1 of the MAPK pathway. The above results indicate that the active ingredients of the compound drug screened by molecular docking have the potential to reduce skin photoaging.
期刊介绍:
The journal Biogerontology offers a platform for research which aims primarily at achieving healthy old age accompanied by improved longevity. The focus is on efforts to understand, prevent, cure or minimize age-related impairments.
Biogerontology provides a peer-reviewed forum for publishing original research data, new ideas and discussions on modulating the aging process by physical, chemical and biological means, including transgenic and knockout organisms; cell culture systems to develop new approaches and health care products for maintaining or recovering the lost biochemical functions; immunology, autoimmunity and infection in aging; vertebrates, invertebrates, micro-organisms and plants for experimental studies on genetic determinants of aging and longevity; biodemography and theoretical models linking aging and survival kinetics.
