PODOPHYLLOTOXINS:

Etoposide and Teniposide are Potent AntiCancer agents which are used Clinically for a variety of conditions such as Testicular Cancer

and small Cell Lung Cancer. They are Semi Synthetic Derivatives of "EPIPODOPHYLLOTOXINS" an isomer of a Naturally Occuring agent

called "PODOPHYLLOTOXIN" where the substituent at position 4 has the opposite configuration.

CAMPTOTHECINS:

CAMPTOTHECINS is a Naturally occuring Cytotoxic alkaloid which was Extracted from a Chinese Bush(Camptotheca Acuminata) in 1966.

It Trgets the Enzyme "TOPOISOMERASE 1". This Enzyme is similar to "TOPOISOMERASE II" in that it relieves the

Torsional stress of supercoiled DNA during replication, Transcription and Repair of DNA.

The difference is that it Cleaves only one strand of DNA, whereas "TOPOISOMERASE II" Cleaves both strands.
