Negamycin Analogue with Readthrough-Promoting Activity as a Potential Drug Candidate for Duchenne Muscular Dystrophy
摘要:
A series of (+)-negamycin 1 analogues were synthesized, and their readthrough-promoting activity was evaluated for nonsense mutations in Duchenne muscular dystrophy 3 (DMD). A structure activity relationship study indicated that 11b was the most potent drug 0 candidate. Immunohistochemical analyses suggested that treatment with 11b restored dystrophin expression in mdx mice, a DMD mouse model. Furthermore, lib decreased serum creatine kinase (CK) levels, an indicator of muscle fiber destruction. Most importantly, 11b demonstrated lower toxicity than 1, and thus, it could be a useful candidate for long-term treatment of DMD.
Provided herein, inter alia, are compositions and methods for generating a immune response in an individual and/or inducing the expression of neoantigens on the surface of abnormal (such as proliferative) cells via promotion of premature termination codon (PTC) read-through and inhibition of nonsense-mediated decay (NMD) of messenger RNAs (mRNAs) bearing PTCs.

Disclosed herein are compositions and methods for treating cancer in a subject. In some embodiments, the methods involve generating an immune response in an individual by inducing the expression of neoantigens on the surface of abnormal (such as proliferative) cells. In one embodiment, a method of treating cancer in a subject includes administering amlexanox in combination with immune modulators, such as checkpoint inhibitors, immune co-stimulatory molecules, TLR agonists, and TNFR superfamily agonists. In one embodiment, the checkpoint inhibitors are selected from antibodies against PD-1, PD-L1, and CTLA-4.
