Efficient and safe delivery of the CRISPR/Cas system is one of the key challenges for genome-editing applications in humans. Herein, we designed and synthesized a series of biodegradable lipidlike compounds containing ester groups for the delivery of mRNA-encoding Cas9. Two lead materials, termed N-methyl-1,3-propanediamine (MPA)-A and MPA-Ab, showed a tunable rate of biodegradation. MPA-A with linear ester chains was degraded dramatically faster than MPA-Ab with branched ester chains in the presence of esterase or in wild-type mice. Most importantly, MPA-A and MPA-Ab demonstrated efficient delivery of Cas9 mRNA both in vitro and in vivo. Consequently, these biodegradable lipidlike nanomaterials merit further development as genome-editing delivery tools for biological and therapeutic

Molecular Therapy
The therapeutic applications of lipid nanoparticle (LNP) formulations of small interfering RNA (siRNA), are hampered by inefficient delivery of encapsulated siRNA to the cytoplasm following endocytosis.
