The present invention also provides a general method to whereby mono-, bi-, or tricyclic heterocycles may be modified to obtain potent antagonists at the NPY
1
receptor.
The present invention provides novel, potent, non-peptidic antagonists of NPY receptors, particularly, the NPY
1
receptors, designed from a selection of mono-, bi-, or tri-cyclic heterocyclic cores.
This invention relates to novel compounds, compositions, and methods for the treatment of physiological disorders associated with an excess of neuropeptide Y. The novel compounds encompassed by the present invention are those of the formula I-XV.

when single bonded to all atoms to which it is attached, or C (carbon) when double bonded to K;
The 6- or 7-membered ring that contains I, J, K, and L may contain from 1 to 3 double bonds, from 0 to 2 heteroatoms, and from 0 to 2 C═O groups, wherein the carbon atom of such groups are part of the ring and the oxygen atom is a substituent on the ring; Q is O or NR
15.
Such compounds inhibit the activity of neuropeptide Y at those receptors are useful in treating physiological disorders associated with an excess of neuropeptide Y, including eating disorders, such as, for example, obesity and bulimia, and certain cardiovascular diseases, for example, hypertension.
本发明还提供了一种通用方法,通过该方法可以改变单环、双环或三环杂环,以获得在NPY1受体上具有强效拮抗作用的化合物。本发明提供了新颖、有效的非肽类NPY受体拮抗剂,特别是NPY1受体拮抗剂,这些化合物是从单环、双环或三环杂环核心的选择中设计出来的。本发明涉及用于治疗与神经肽Y过量相关的生理疾病的新化合物、组合物和方法。本发明所涵盖的新化合物的公式为I-XV.123,其中X为N或CR14; W为S、O或NR15; Y为N或CR3; E、F和G各自独立地为CR3或N; I和J各自独立地为C═O、S、O、CR3R16或NR15,当与相邻的环原子形成单键时,或为N或CR3,当与相邻的环原子形成双键时;K为N或CR3,当与L或J形成双键时,或为O、S、C═O、CR3R16或NR15,当与相邻的环原子形成单键时,或为N或CR3,当与相邻的环原子形成双键时;L为N或CR16,当与其连接的所有原子形成单键时,或当与K形成双键时为C(碳);包含I、J、K和L的6-或7成员环可能包含从1到3个双键,从0到2个杂原子和从0到2个C═O基团,其中这些基团的碳原子是环的一部分,氧原子是环上的取代基;Q为O或NR15。这些化合物可以抑制神经肽Y在受体上的活性,对于治疗与神经肽Y过量相关的生理疾病,包括进食障碍,例如肥胖症和暴食症,以及某些心血管疾病,例如高血压,具有用途。
