Mesoporphyrin IX
Mesoporphyrins:
They are degradative products of Haemin.
If Iron is removed &vinyl group is reduced to Ethyl, then 15
Mesoporphyrins with 4 pyrrole moiety are possible.
One of them is Mesoporphyrins IX.
This is identical with Mesoporphyrin obtained from Haemin.
Haemin-
Protin free fragment.
Responsible for the colour of Blood.
Involves in Oxygen transfer.
Belongs to general class of compounds known as "Porphyrine".
"Hans Fischer" carried out a very extensive work & established its
structure.
4
Large no. of degradative products was studied.
To synthesized Mesoporphyrins:- pyrrole derivatives synthesized.
Pyrrol (3) + Pyrrole (4)
A & B ring
Pyrrole (8)
C & D ring.
*Synthesis of substituted pyrrole:-
