J Masson Gulland and Robert Robinson | deciphered the chem structure of morphine robert won the nobel prize in 1947 |
morphine today | Morphine, and related opioid alkaloids, remain the most effective method for the treatment of severe pain.action of morphine is due to its agonism of the mu (m) opioid receptor in the CNS |
Cinchona Bark | Jesuits in 17th cen SA used it to cure malaria. cure brought to europe ROBERT TALBOR used it to cure kings |
Joseph Pelletier and Joseph Bienaime Caventou | isolated the active principle of cinchona--> QUININE in 1820. they opened 2 factories 3600kg of yearly quinine sulfate. |
Paul Rabe | proposed the correct structure of quinine (1907) .. later confirmed by a total synthesis by robert b woodward |
Robert Woodward | formal synthesis of quinine... maser of the art of organic synthesis. led to nobel prize 1965 |
quinine today | no longer used due to parasitic resistance related derivatives are used. prohoylacticatlly and for treatment of the diease (chloroquine and Mefloquin) |
Epinephrine (adrenaline) | 1900-1910vasoconstrictor injected intramuscularly or intravenously to raise blood pressure or relieve anaphylaxis in the case allergic It is also injected subcutaneously to locally constrict blood vessels and thus prolong the action of local anesthetics |

Dorothy Crowfoot Hodgkin | used xray crystallography to obtain the 1st crystal structure of insulin. nobel 1964 for work on the xray crys techniq |
Suldanilamide | (antiinfective)The sulfa drugs represented the first highly effective antibiotics and saved thousands of lives |
sulfa drugs today | very old antibiotics but still used today used by forming combo mixture co-trimoxazole |
target of penicillins | target of the penicillins are the PBPs (penicillin binding proteins) transpeptidases responsible for cross-linking peptidoglycan strands |
