A conjugate of oligonucleotides and bile acid derivatives having the structure (I), (II) or (III), pharmaceutical compositions thereof, and uses thereof are described.
Fifteen berberine–bile acid analogues were synthesized. Anticancer activities of these analogues compared with
berberine (BBR) were evaluated in vitro; among the analogues, A4, B4, and B5 had higher cytotoxicity than that of BBR.
Most of the analogues showed higher antimicrobial activity against Staphylococcus aureus ATCC 25923 and
Staphylococcus albus ATCC 8799 than that of BBR, but Bacillus subtilis AS 1.398 and Escherichia coli ATCC 31343
were not sensitive to all of the analogues. A4 and B4 were stable in the serum stability assay. B4 showed promising oral
bioavailability in mice.
In accordance with the present disclosure, compounds have been discovered that bind to PD-L1 and are capable of inhibiting the interaction of PD-L1 with PD-1 and CD80. These macrocyclic compounds exhibit in vitro immunomodulatory efficacy thus making them therapeutic candidates for the treatment of various diseases including cancer and infectious diseases.
