In order to find the minimal structural requirements to maintain microtubule binding, 12 taxol analogues have been docked to the taxol binding site of tubulin. By comparing the interactions of each analogue with β-tubulin, the structure-activity relationships are summarized as follow: C-2 benzoyl and taxane ring systems are the essential groups for microtubule binding, the improvements of bioactivity and bioavailability are dependent on the substituents at positions C-1, C-4, C-7, C-9, C-10, and C-14, whereas the C-13 side chain mainly provides a specific binding.

Dammarane-type ginsenosides are a class of tetracyclic triterpenoids with the same dammarane skeleton. These compounds have a wide range of pharmaceutical applications for neoplasms, diabetes mellitus and other metabolic syndromes, hyperlipidemia, cardiovascular and cerebrovascular diseases, aging, neurodegenerative disease, bone disease, liver disease, kidney disease, gastrointestinal disease and other conditions. In order to develop new antineoplastic drugs, it is necessary to improve the bioactivity, solubility and bioavailability, and illuminate the mechanism of action of these compounds. A large number of ginsenosides and their derivatives have been separated from certain herbs or synthesized, and tested in various experiments, such as anti-proliferation, induction of apoptosis, cell cycle arrest and cancer-involved signaling pathways. In this review, we have summarized the progress in structural modification, shed light on the structure-activity relationship (SAR), and offered insights into biosynthesis-structural association. This review is expected to provide a preliminary guide for the modification and synthesis of ginsenosides.
