A variety of small, guanidino group-containing molecules capable of acting as MC4-R agonists are provided. The compounds have various structures provided herein. The compounds are useful in treating MC4-R mediated diseases and may be formulated into pharmaceutical formulations and compositions.
The present invention relates to materials used for aligning liquid crystals of liquid crystal display elements and to a polymer for use in liquid crystal vertical alignment layer used in producing a liquid crystal vertical alignment layer.
The polymer for use in a liquid crystal vertical alignment layer includes (a) a moiety that is photochemically isomerizable but not photochemically crosslinked, (b) a moiety that is photochemically crosslinkable, and (c) a moiety that stabilizes a vertical alignment. The polymer can be used to produce a vertical alignment layer that has a liquid crystal alignment property enabling control of alignment at a low UV dose and that offers a large pretilt angle and superior optical stability.

The Mn-III-induced addition of malonic acid (instead of acetic acid) to cinnamic esters affords in one step functionalized trans-3,4-disubbtituted-gamma-butyrolactones in a greatly improved yield which can be further optimized by conducting the reaction in either acetic or formic acid, depending on the substrate.
