Irinotecan is a hydrophilic compound with a large volume of distribution (400 L/m 2). [20] [21] At physiological pH, irinotecan and its active metabolite ethyl-10-hydroxy-camptothecin (SN-38) are present in two pH-dependent equilibrium isoforms; the anti tumor active lactone ring which hydrolyzed to the carboxylate isoform. [21]
It is the active metabolite of irinotecan (an analog of camptothecin - a topoisomerase I inhibitor) but has 1000 times more activity than irinotecan itself. In vitro cytotoxicity assays show that the potency of SN-38 relative to irinotecan varies from 2- to 2000-fold.

Camptothecin (CPT) is a topoisomerase inhibitor.It was discovered in 1966 by M. E. Wall and M. C. Wani in systematic screening of natural products for anticancer drugs.It was isolated from the bark and stem of Camptotheca acuminata (Camptotheca, Happy tree), a tree native to China used in traditional Chinese medicine.
Fetal resorption (also known as fetus resorption) is the disintegration and assimilation of one or more fetuses in the uterus at any stage after the completion of organogenesis, which, in humans, is after the ninth week of gestation.
Anatomy scan of the fetal head at 20 weeks of pregnancy in a fetus affected by spina bifida. In the axial scan the characteristic lemon sign and banana sign are seen. Anatomy scan with power bi-directional colour Doppler of both fetal kidneys at 18 weeks of pregnancy to detect renal agenesis. The videoclip shows a frontal scan with normal renal ...
