A compound of formula (1a), (1b) or (1c) wherein: n is 1 or 2; R.sup.N is H or Me; R.sup.1 is optionally one or more halo or methyl groups; R.sup.2a and R.sup.2b are independently selected from the group consisting of: (i) F; (ii) H; (iii) Me; and (iv) CH.sub.2OH; R.sup.2c and R.sup.2d (if present) are independently selected from the group consisting of: (i) F; (ii) H; (iii) Me; and (iv) CH.sub.2OH; R.sup.3a and R.sup.3b are independently selected from H and Me; R.sup.4a is selected from OH, NH.sub.2, C(O)NH.sub.2, and CH.sub.2OH; R.sup.4b is either H or Me; R.sup.5 is either H or Me; A is either (i) optionally substituted phenyl; (ii) optionally substituted naphthyl; or (iii) optionally substituted C.sub.5-12 heteroaryl. ##STR00001##

A structure of the compound containing a diphenylmethane structure of the present invention is represented by General Formula (1). The compound containing a diphenylmethane structure of the present invention contains a hydroxyl group, an amino group, a substituted amino group, and an active group, and can be used as an amino acid or peptide C-terminal protection reagent. A peptide synthesis reaction using this protection carrier has a fast reaction speed and a high reagent utilization rate in a suitable solvent system; post-treatment is carried out by means of simple liquid-liquid extraction separation, i.e. effective purification can be carried out, and finally, a product with a high purity can be obtained; and during a synthesis process, the change in solubility is small and an operation process has a strong universality, and therefore, the present method can be developed into a universal production method.

The present disclosure relates to ionizable lipidoid compounds comprising an anisamide moiety, and lipid nanoparticles (LNPs) comprising the same. In certain embodiments, the LNP selectively binds to at least one sigma receptor. In certain embodiments, the LNP specifically targets a cell of interest (e.g., a cell expressing a sigma receptor, fibroblast, cancer cell, stromal cell, and epithelial cell, inter alia). In another aspect, the present disclosure provides methods for in vivo delivery of therapeutic agents to treat, prevent, and/or ameliorate diseases and/or disorders, including but not limited to fibrosis and cancer.
