. The Schiff's bases and their metal complexes of the present invention are useful for the modulation of metal-activated enzymes and metalloenzymes, such as Phenylalanine Hydroxylase, Tyrosine Transaminase, Phenylalanine Transaminase, Tyrosinase, various MMP (Matrix metalloproteases), Superoxide dismutase, 5-Alpha Reductase, and citrate lyase. These are further suitable for multifunctional topical methods for skin whitening, skin wrinkles reduction, skin antiaging, collagen synthesis, acne control, hair loss prevention, hair graying control, and facial oil control.
本发明涉及从氨基酸和羟基芳基烷基酮衍生的席夫碱,或含有该类化合物的植物提取物,其具有图1中的一般化学结构,用于局部应用。本发明还涉及所述席夫碱的某些金属配合物,其在三维化学结构中呈冠状外观,如图2所示。本发明的席夫碱及其金属配合物对于调节金属活化酶和金属酶,例如苯丙氨酸羟化酶、酪氨酸转氨酶、苯丙氨酸转氨酶、酪氨酸酶、各种基质金属蛋白酶、超氧化物歧化酶、5α-还原酶和柠檬酸裂解酶具有用途。此外,它们还适用于多功能局部方法,如美白肌肤、减少皮肤皱纹、抗衰老、胶原蛋白合成、控制痤疮、预防脱发、控制白发和面部油脂控制。
