http://en.wikipedia.org/wiki/Catharanthus
(the genus name for Madagascar periwinkle)

US and Taiwan alike.
(i) vincristine
http://en.wikipedia.org/wiki/Vincristine
(approved by the United States Food and Drug Administration (FDA) in July
1963 as Oncovin)
Quote:
Vincristine is a vinca alkaloid from the Catharanthus roseus (Madagascar
periwinkle), formerly Vinca rosea and hence its name.
"Vincristine binds to tubulin dimers, inhibiting assembly of microtubule
structures. Disruption of the microtubules arrests mitosis in metaphase. The
vinca alkaloids therefore affect all rapidly dividing cell types including
cancer cells, but also intestinal epithelium and bone marrow.
(e) Mechanism of the Gleevec.
Most chronic myelogenous leukemia (CML) patients share a distinctive feature
described in 1960 by two scientists from Philadelphia. The reciprocal
translocation switches ends of chromosomes 9 and 22 with each other (the
resultant chromosome 22 is the Philadelphia chromosome). As a result, part
of the BCR ("breakpoint cluster region") gene from chromosome 22 is fused
with the ABL gene on chromosome 9.
The abl stands for "Abelson", the name of a leukemia VIRUS (in mouse) which
carries a similar protein whose gene the virus grabbed from a host in
ancient time to help itself proliferate. ABL (all upper cases) is the normal
counterpart in almost all living cells that performs vital functions--
basically an enzyme that can add a phosphate group to a certain tyrosine
residue of a tyrosine kinase, therefore activating that kinase. In
Philadelphia chromosome, the ABL portion of the fusion protein is stuck in a
perpetually active position, which somehow causes cancer. (Why? Nobody
knows.)
Gleevec specifically binds to, blocks and inactivates the ABL portion of the
fusion protein.

(i) For ramamycine, see sirolimus
http://en.wikipedia.org/wiki/Sirolimus
(an immunosuppressant drug used to prevent rejection in organ
transplantation; was first discovered as a product of the bacterium
Streptomyces hygroscopicus in a soil sample from Easter Island — an island
also known as "Rapa Nui", hence the name)
(ii) The origin of "Rapa Rui" name:

Rapa Iti
http://en.wikipedia.org/wiki/Rapa_Iti
Rapa Iti was originally called simply Rapa. Iti ("small" in the local
Polynesian language) was added to distinguish Rapa Rui, which was actually
named after Rapa (Iti).
(iii) mammalian target of rapamycin
http://en.wikipedia.org/wiki/Mammalian_target_of_rapamycin
(mTOR; a serine/threonine protein kinase)
A serine/threonine protein kinase is a (protein) kinase which is activated
by adding a phosphate to a certain serine or threonine of that kinase--as
opposed to tyrosine of a tyrosine kinase--and activate the kinase.
The serine, threonine and tyrosine are amino acids, components of a protein.
