Three S-peptide analogues of bovine pancreatic ribonuclease A (RNase A), [Nle1] [Lys7] S-peptide (I), [Lys1] [Nle7] S-peptide (II) and [Nle1] [Nle7] S-peptide (III), were synthesized by the fragment condensation method and their ability to reactivate S-protein was examined. It was found that Lys1 and Lys7 both have roles in the reactivation of S-protein.
采用片段缩合法合成了牛胰腺核糖核酸酶 A(RNase A)的三种 S 肽类似物,即 [Nle1] [Lys7] S 肽(I)、[Lys1] [Nle7] S 肽(II)和 [Nle1] [Nle7] S 肽(III),并考察了它们重新激活 S 蛋白的能力。结果发现,Lys1 和 Lys7 都在 S 蛋白的再活化过程中发挥作用。

Lithiumaluminumhydride reduction of the oximes derived from quinidinone (IIIa) and cinchonidinone has been used to obtain 9-amino-(9-deoxy)quinidine (IIb) and the corresponding 9-amine in the cinchonine series. Based on optical rotatory dispersion measurements, tentative stereochemical assignments for the amines have been proposed. A major objective of the present study, synthesis of 9-(benzylox
