am an MBA student (also, a Ph.D. in biochemistry) who is in the
process of writing a business plan as a class assignment. In the
context of this assignment, I was wondering if anyone might be
able to suggest natural products which fit the following criteria:

Natural products which a

1) Impossible, extremely difficult, or extremely expensive to synthesize in bulk

2) Hard or inefficient to isolate from natural sources

3) Of commercial interest to pharmaceutical, vitamin, food, or cosmetic industries

4) The biosynthetic pathway (genes) has been outlined

Number 4 is not absolutely necessary; #1-3 are. Suggestions would be
welcome.
