In accordance with preferred embodiments of the present invention, a method for imaging tissue, for example, includes the steps of mounting the tissue on a computer controlled stage of a microscope, determining volumetric imaging parameters, directing at least two photons into a region of interest, scanning the region of interest across a portion of the tissue, imaging a plurality of layers of the tissue in a plurality of volumes of the tissue in the region of interest, sectioning the portion of the tissue and imaging a second plurality of layers of the tissue in a second plurality of volumes of the tissue in the region of interest, detecting a fluorescence image of the tissue due to said excitation light; and processing three-dimensional data that is collected to create a three-dimensional image of the region of interest.

The present invention provides a compound represented by the following formula (I): wherein: Ring A represents an optionally substituted piperazine ring, an optionally substituted morpholine ring, or an optionally substituted bromopiperazine ring; R1 and R2 are the same or different from each other, and represent a hydrogen atom or optionally substituted lower alkyl; R3 and R4 are the same or different from each other, and represent a hydrogen atom or halogenated or non-halogenated lower alkyl; R3 to R7 are the same or different from each other, and represent a hydrogen atom, hydroxy, optionally substituted lower alkyl, optionally substituted lower alkenyl, optionally substituted lower alkoxy, optionally substituted cycloakyl, optionally substituted aryl, an optionally substituted aromatic heterocyclic ring, optionally substituted amino, or acyl; and represents a single bond or double bond, wherein R2 and R3 do not exist when carbon atoms respectively adjacent to R2: and R3 form a double bond, and there is no case where all of R1 to R7 are hydrogen atoms, and R1 and R2; may form a ring together with an adjacent carbon atom; or a salt thereof.

The present invention provides a compound having a superior PDE10A inhibitory action and use thereof. The compound is a compound represented by the following formula (I):wherein each symbol is as defined in the present specification, or a salt thereof.

Compounds and methods for determining transmembrane potential, monitoring changes in transmembrane potential, and / or drug screening are provided. In one aspect, compounds of the invention have a structure according to the formula: E-M-A, wherein A is a fluorophore, selected from xanthenes, coumarins, cyanines, bimanes, and difluoroboradizaindacenes, charged at physiological pH; M is a molecular wire; and E is a hydrophobic moiety, wherein A and E are capable of being involved in a photo-induced, intramolecular electron transfer that quenches the fluorescence of A in response to a voltage condition. When in use, compounds of the invention are membrane-impermeant and oriented within the cell membrane such that the charged moiety localizes at the outer leaflet of the lipid bilayer and the hydrophobic moiety and molecular wire associate with the hydrophobic portion of the lipid bilayer. The rate of electron transfer, fluorescence intensity, and quenching are altered in response to changes in transmembrane potential.

Compounds are disclosed that are useful for treating ophthalmic conditions caused by or related to production of toxic is visual cycle products that accumulate in the eye, such as dry adult macular degeneration, as well as conditions caused by or related to the misfolding of mutant opsin proteins and / or the mis-localization of opsin proteins. Compositions of these compounds alone or in combination with other therapeutic agents are also described, along with therapeutic methods of using such compounds and / or compositions. Methods of synthesizing such agents are also disclosed.
