Daim tawv nqaij - tsaus nti peptides yog ib chav kawm ntawm polypeptides uas txhawb kev tsim melanin hauv daim tawv nqaij, muaj cov tawv nqaij - tsaus nti, tiv thaiv - mob, photoprotective, thiab muaj peev xwm tiv thaiv - cov teebmeem ntawm daim tawv nqaij. Cov tshuaj no ua tiav cov tawv nqaij tawv tawv los ntawm kev ua kom cov melanin receptors (xws li MC1R), stimulating melanocyte proliferation thiab melanin synthesis.
Cov tawv nqaij ntau- tsaus nti peptides suav nrog:
Melanotan II: Ib qho hluavtaws cyclic polypeptide hormone uas muaj peev xwm ua kom cov melanin receptors, txhawb cov tawv nqaij pigmentation. Nco ntsoov tias nws txoj kev siv muaj kev pheej hmoo; Kev siv tsis raug yuav ua rau muaj qhov tshwm sim ntawm kev tsim melanoma.
Myristoyl Tetrapeptide-20: Txhawb nqa melanin ntau lawm los ntawm cov tshuaj tiv thaiv cascade thiab tseem muaj cov tshuaj tiv thaiv tseem ceeb - mob, tiv thaiv UV puas tsuaj, thiab kev tiv thaiv kev yees duab; nws yog feem ntau siv nyob rau hauv cov tshuaj pleev ib ce formulations.
Afamelanotide: Ib daim tawv nqaij -peptide lightening pom zoo rau kev kho mob ntawm erythropoietic protoporphyria (EPP), uas zoo txhim kho daim tawv nqaij tolerance rau lub teeb. Txawm hais tias nws qhia tau tias muaj peev xwm nyob rau hauv kev cai xim, nws tsis yog tam sim no ib qho kev kho mob rau vitiligo.
