Sulfonamides
Nh2 → should be para position , un substituent except acylation .
→ Essential for activity. Substitution at( ortho or meta) position
destroys Activity .

1-sulfonamido for systemic infection : orally
2- intestinal :
3-opthalmic I :
sulfacetamide sodium.
4- burn :
Silver sulfadiazine is very slightly soluble and not absorbed and releases
sulfadiazine slowly .

______________________________________________________________________________
Isoniazid (INH):
Ethionamide :
Dapsone :
TTT → leprosy .
m.o.a : like sulfonamide
Mood of action :
Inhibit Bactria DNA . through competitive to PABA .
SAR of Pamaquine or 8-Aminoquinolines :
1) 6-Methoxy group is not essential,(6-hydroxyl)is quite active, 6-ethoxyl
has little activity
while 6-methyl is inactive.
2 ) Additional substituent on the aromatic ring tend to decrease both
activity and toxicity.
3 ) Reduction of the quinoline ring, retain the activity but lower the potency
and toxicity.
