Modulators of ATP-Binding Cassette transporters
Compounds of the present invention and pharmaceutically acceptable compositions thereof, are useful as modulators of ATP-Binding Cassette (“ABC”) transporters or fragments thereof, including Cystic Fibrosis Transmembrane Conductance Regulator (“CFTR”). The present invention also relates to methods of treating ABC transporter mediated diseases using compounds of the present invention.
1. A compound selected from
2. A pharmaceutical composition comprising a compound according to claim 1 and a pharmaceutical carrier.
3. A method of increasing CFTR transporter activity comprising the step of contacting said CFTR transporter with a compound selected from
4. A method of treating or lessening the severity of cystic fibrosis comprising the step of administering to said patient an effective amount of a compound according to claim 1 .
5. A kit for use in measuring the activity of a CFTR transporter or a fragment thereof in a biological sample in vitro or in vivo, combining:
(i) a composition comprising a compound according to claim 1 ; and
(ii) instructions for:
a) contacting the composition with the biological sample; and
b) measuring activity of said CFTR transporter or a fragment thereof.
6. The kit of claim 5 , further comprising instructions for
a) contacting an additional composition with the biological sample;
b) measuring the activity of said CFTR transporter or a fragment thereof in the presence of said additional compound; and
c) comparing the activity of the CFTR transporter in the presence of the additional compound with the density of the CFTR transporter in the presence of a compound selected from.
