linoleic acid, trigonelline, camptothecin, 9-O-methoxycamptothecin and pumiloside were isolated and characterized from the stem of Nothapodytesfoetida. Among them, scopoletin, camptothecin, 9-O-methoxycamptothecin and O-acetylcamptothecin showed significant cytotoxic activity.
The invention relates to polymers, such as aliphatic polyesters, with grafted zwitterions. More particularly, the invention relates to polyester-graft-phosphorylcholine polymers prepared by ring-opening polymerization and click chemistry, compositions and products comprising same, and related methods and uses, for example, in drug delivery.
