(57) Abstract: The present invention provides a useful heterocyclic compounds in the regulation of muscarinic receptors.

The present invention is also a process for preparing the compounds described above, and pharmaceutical compositions containing them, as well as to the use of these.

The present invention provides an antimicrobial agent to novel oxazolidinone derivatives and containing the same formula (I) with organic residue capable of binding to the 5-position of the ring.

The present application provides compounds of formula (I) that modulate the activity of stearoyl-CoA desaturase and pharmaceutical compositions comprising such derivatives.

Main aim of this paper is to present the information regarding the Heterocyclic compounds that constitute the largest family of organic compounds. These are extremely important with wide array of synthetic, pharmaceutical and industrial applications. There is always a strong need for new and efficient processes in synthesizing of new Heterocycles. Several 1,3,4,5-tetraaryl-2 pyrazoline, 41 -piperazine, 3- methoxybenzofuran and thiazolidin-4-one substituted 1, 2, 4-triazole, 4- NO2, 2-OH and 4-Cl in phenyl ring at 5- position of pyrazoline ring of synthesized compounds. The new compounds were c...

Is intended to provide a useful novel materials as organic electroluminescence element material, fused three 5-membered ring on the benzene ring, furthermore, saturated or unsaturated ring on the 5-membered ring is condensed below heterocyclic compounds represented by the general formula (1) is an organic electroluminescence element material, and organic electroluminescent devices and an electronic device using the same using the same. [In the general formula ]

The IUPAC Gold Book describes heterocyclic compounds as: “Cyclic compounds having as ring members atoms of at least two different elements, e.g. quinoline, 1,2-thiazole, bicyclo[3.3.1]tetrasiloxane” [1]. Usually they are indicated as counterparts of carbocyclic compounds, which have only ring atoms from the same element. Another classical reference book, the Encyclopaedia Britannica, describes a heterocyclic compound, also called a heterocycle, as: “Any of a class of organic compounds whose molecules contain one or more rings of atoms with at least one atom (the heteroatom) being an element ot...

The present invention relates to novel N-substituted azaheterocyclic carboxylic acids and esters thereof to methods for their preparation, to compositions containing them, and to their use for the clinical treatment of painful, hyperalgesic and/or inflammatory conditions in which C-fibers play a pathophysiological role by eliciting neurogenic pain or inflammation.

Compound (I), or relates to a pharmaceutically acceptable salt thereof to interferon inducing agent, a therapeutic agent of the antibacterial agents, anticancer agents and immunogenic diseases containing as an active ingredient.
