Sorangicin A

Class: RNA Polymerase inhibitor

Spectrum of activity:	Gram-positive  &  Gram-negative
Details of activity:	Inhibits RNA polymerase. Broad Spectrum but more potent against Gram positives. Specifically active against Mycobacteria(2)
Institute where first reported:	Ciba-Geigy (Novartis, Switzerland)
Year first mentioned:	1986
Development status:	Inactive
Reason Dropped:	Demonstrates partial cross resistance with rifamycins due to partial overlap in binding site but has ' potential promise as an antituberculosis agent effective against a subset of rifamycin-resistant bacterial infections' (2)
