Glycotriazole-peptides derived from the peptide HSP1: synergistic effect of triazole and saccharide rings on the antifungal activity.

abstract：:Glioma is the most common type of brain tumor, and has the worst prognosis in human malignancy. Experimental evidence suggests that the use of high concentrations of various amino acids may perturb neoplastic cell growth. Thus, the aim of this study was to investigate whether essential amino acids can alter the growth...
