Methods and compositions for treating bacterial infection
The present disclosure relates to chemical compounds, methods for their discovery, and their therapeutic and research use. In particular, the present disclosure provides compounds as therapeutic agents against bacterial infections (e.g., biofilms). The present disclosure also provides topical formulations for use in methods for treating bacterial infections.
1. A topical formulation for treating a bacterial infection comprising:
a compound having the structure of Formula V
wherein X is SR 1 , NH 2 , NHR 1 , NR 1 R, OH, OR 1 , or Cl; wherein R and R 1 are, independently, H, a C1-C8 alkyl or alkenyl or cycloalkyl, optionally substituted with F, CN, OR 6 , NR 6 2 , COR 6 , CO 2 R 6 , CONHR 6 , aryl or heteroaryl, wherein one or more alkyl carbons may be replaced by O; R 2 is H or a Cl alkyl; R 3 and R 4 are, independently, a C1-C8 alkyl; R 5 is C1-C6 alkyl, CN, OR 6 , NR 6 2 , COR 6 , CO 2 R 6 , CONHR 6 , aryl, heteroaryl, SO 2 R 6 , NHCOR 6 , SO 2 NHR 6 , or OCOR 6 ; R 6 is H, C1-C6 alkyl, C0-C3 alkyl-aryl, or C0-C3 alkyl-heteroaryl, all optionally substituted; and R 11 is H or a C1 alkyl; and
a base comprising a hydrocarbon base, an oil, and combinations thereof.
2. The topical formulation of claim 1 , wherein the compound is selected from the group consisting of:
