Molecular things you have Organic Synthesis chemists ? Molecular things you want
Nam Le Molecular things you have Molecular things you want
Synthesis Requires Two Things 1. a library of reactions 2. a strategy or plan for combining known reactions to reach the desired target molecule 3. and a little luck always helps
goal (a desired molecular structure)
Work the problem from the final goal toward the reactants. Have a library of reactions that connect a goal to a subgoal. subgoal-1a subgoal-1b subgoal-2a subgoal-2b subgoal-3a subgoal-3b goal
Work the problem from the final goal toward the reactants. Have a library of reactions that connect a goal to a subgoal. Using your knowledge of each reaction select the best pathway as your solution to the synthetic problem.

Discodermolide The result of biological studies stimulated considerable interest in discodermolide as a possible immunosuppressant. Subsequently studies demonstrated discodermolide is a potent cell growth inhibitory agent, which arrests cell development at the M phase by binding and stabilizing mitotic spindle microtubules. Thus, the ability of (+)-1 to inhibit cell growth was suggested to resemble the clinically proven anticancer agent Taxol.
Discodermolide isolated from a marine sponge
Discodermolide Some problems with pharmaceuticals from natural sources: Quantities can be very limited. The isolation process can be very expensive. Industrial production can destroy valuable ecosystems. More active structural variants are not available from nature.
