Three peptide fragments of STF, H-Ser-Gln-Gly-Gly-Ser-Asn-OH, H-Lys-Ser-Gln-Gly-Gly-Ser-Asn-OH and H-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn-OH, were synthesized by the solution method and their biological activities were investigated. The minimum fragment of STF able to show antagonistic action towards the E-rosette formation inhibition activity of MMS appears to be H-Lys-Ser-Gln-Gly-Gly-Ser-Asn-OH.
通过溶液法合成了STF的三个肽片段,分别为H-Ser-Gln-Gly-Gly-Ser-Asn-OH、H-Lys-Ser-Gln-Gly-Gly-Ser-Asn-OH和H-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn-OH,并对其
生物活性进行了研究。STF中能够对
MMS的E-玫瑰花结形成抑制活性产生拮抗作用的最低片段似乎是H-Lys-Ser-Gln-Gly-Gly-Ser-Asn-OH。
