Synthesis and Antibacterial Activity of 6-Substituted Amino Purine Derivatives 6-取代胺基嘌呤衍生物的制备及抗菌活性研究
These changes show that in the process of HeLa cells 'growth, UV absorption spectrum reflects the close relationship among the aromatic amino acids, purine and pyrimidine derivatives and HeLa cell growth process. 这些变化说明HeLa细胞生长过程中紫外吸收光谱的变化反映了芳香族氨基酸、嘌呤和嘧啶衍生物与HeLa细胞生长过程的密切关系。
