The invention provides non-centrosymmetric organic crystals which show exceptional self-healing properties. More particularly, the present invention provides non-centrosymmetric substituted imidazole and Dialkyl 4,4′-methylenebis(azanediyl)dibenzoate Crystals and a process for preparation thereof. These highly crystalline materials, when broken into pieces, can self-propel and re-join in the blink of an eye and repair themselves so precisely that they become indistinguishable from the undisturbed materials.

Provided are a polypeptide having excellent 4-aminobenzoic acid hydroxylation activity and a method for using the same. The present invention provides a polypeptide having 4-aminobenzoic acid hydroxylation activity, consisting of the amino acid sequence represented by SEQ ID NO: 2 or an amino acid sequence having at least 47% identity thereto, and having an amino acid residue at position 47 of the amino acid sequence represented by SEQ ID NO: 2 or a position corresponding thereto being leucine.

The present disclosure provides an antibacterial hydrophilic compound. The antibacterial hydrophilic compound may react, induced by light through a hydrogen abstraction group in the structural formula thereof, with a C—H group and thus bind to a surface of a material having the C—H group (for example, chemical fibers such as polyester, chinlon, and the like; plastics, rubbers, and other similar materials), which can impart a durable antibacterial activity and hydrophilicity to the material. The antibacterial hydrophilic compound has a relatively strong binding force to the surface of the material without damaging the mechanical properties of the raw material. The present disclosure also provides a modified material that is modified by the antibacterial hydrophilic compound.

Compositions and methods for treating macular degeneration and other forms of retinal disease whose etiology involves the accumulation of A2E and/or lipofuscin, and, more specifically, for preventing the formation and/or accumulation of A2E are disclosed.
