Two new analogues of serum thymic factor (STF), [Dab3]- and [Asn5, Gln9]-STF and four thymic factor fragments, H-Lys-Ser-Gln-OH, H-Lys-Ser-Gln-Gly-OH, H-Lys-Ser-Gln-Gly-OH and H-Lys-Ser-Gln-Gly-Gly-Ser-OH, were synthesized by the solution method, and were tested to determine their effects on the low E-rosette forming cells in patients with chronic renal failure. The analogue [Dab3]-STF and three fragments, H-Lys-Ser-Gln-Gly-OH, H-Lys-Ser-Gln-Gly-Gly-OH and H-Lys-Ser-Gln-Gly-Gly-Ser-OH, increased E-rosette forming capacity when incubated in vitro with patient's blood, but [Asn5, Gln9]-STF and the tripeptide, H-Lys-Ser-Gln-OH, had no effect.
通过溶液法合成了两种新型的血清胸腺因子(STF)类似物[Dab3]-STF和[Asn5, Gln9]-STF,以及四种胸腺因子片段H-Lys-Ser-Gln-OH、H-Lys-Ser-Gln-Gly-OH、H-Lys-Ser-Gln-Gly-OH和H-Lys-Ser-Gln-Gly-Gly-Ser-OH,并测试了它们对慢性肾衰竭患者低E玫瑰花结形成细胞的影响。类似物[Dab3]-STF和三种片段H-Lys-Ser-Gln-Gly-OH、H-Lys-Ser-Gln-Gly-Gly-OH和H-Lys-Ser-Gln-Gly-Gly-Ser-OH在体外与患者血液孵育时增加了E玫瑰花结形成能力,而[Asn5, Gln9]-STF和三肽H-Lys-Ser-Gln-OH则没有效果。
