Quinazoline derivative from indigenous isolate, Nocardiopsis alba inhibits human telomerase enzyme.

Aim: Aim of this study was isolation and screening of various secondary metabolites produced by indigenous isolates of soil Actinomycetes for human telomerase inhibitory activity.

Methods And Results: Extracellular extract from culture suspension of various soil Actinomycetes species were tested for telomerase inhibitory activity. The organism which produced telomerase inhibitor was identified by 16S rRNA gene sequencing.
