effects tended to become stronger with increasing length of the acyl chain. 2-O-α-d-Glucopyranosyl-6-O-hexadecanoyl-l-ascorbic acid (6-sPalm-AA-2G), which has a straight C16 acyl chain, was the most potent effective for inhibition of hyaluronidase activity and for inhibition of degranulation among the 6-sAcyl-AA-2G derivatives and the two isomers of 6-sPalm-AA-2G. Furthermore, percutaneous administration
2-O-α-d-Glucopyranosyl-1-抗坏血酸(AA-2G)是一种稳定的抗坏血酸(AA)衍生物,被称为原维生素C剂。我们以前合成了AA-2G的两种单酰化衍生物,即6-O-酰基-2-O-α-d-吡喃吡喃糖基-1-抗坏血酸,其直链长度从C 1到C 18不等(6- sAcyl-AA-2G)和从C 1至C 16长度可变的支链酰基链(6-bAcyl-AA-2G),以提高AA-2G的生物利用度。在这项研究中,6-sAcyl-AA-2G和6-bAcyl-AA-2G本身显示出对透明质酸酶活性和脱粒的抑制作用。6-sAcyl-AA-2G对透明质酸酶活性和脱粒作用表现出强烈的抑制作用,且呈浓度依赖性,并且随着酰基链长度的增加,抑制作用趋于增强。具有直链C16酰基链的2-O-α-d-Glucopyranosyl-6-O-十六烷酰基-1-抗坏血酸(6-sPalm-AA-2G)最有效地抑制透明质酸酶活性
