A series of new 1, 4-benzoxazine derivatives (XI, XII) possessing (4-phenyl-1-piperazinyl)alkyl moieties at the 2-position and related compounds (XIII) were synthesized and tested for calcium antagonistic, calmodulin antagonistic and antihypertensive activities. Various compounds had in vitro calmodulin antagonistic activity superior or comparable to that of trifluoperazine. Among these compounds, tetrahydronaphtho[2, 3-b][1, 4]oxazine derivatives such as 51, 53, 54, 58, 59, 60, 73 and 75 showed potent antihypertensive effects in spontaneously hypertensive rats. Optical isomers of 51 were also synthesized and evaluated biologically. No differences in biological activities were seen between the enantiomers.
The present invention is concerned with new 3,3-disubstituted indol-2-one derivatives of the general Formula (I), wherein R
1
stands for hydrogen, halogen, alkyl having 1-7 carbon atom(s) or sulfonamido; R
2
represents hydrogen or halogen; R
3
denotes hydrogen, alkyl having 1-7 carbon atom(s) optionally carrying an aryl substituent or aryl optionally carrying one or two halogen substituent(s); R
4
stands for alkyl having 1-7 carbon atom(s); R
5
represents a group of the general Formula (II a) or (II b), wherein Q and W each represents nitrogen or CH; R
6
, R
7
and R
8
each stands for hydrogen, halogen, trifluoromethyl, alkyl or alkoxy having 1-7 carbon atom(s), or R
6
and R
7
together represent ethylenedioxy; m is 0, 1, or 2; a is a single, double or triple bond; n is 0, 1 or 2; and pharmaceutically acceptable acid addition salts thereof which are useful in the treatment or prophylaxis of diseases of the central nervous system, the gastrointestinal system and the cardiovascular system.

Heterocyclic compounds as Weel inhibitors are provided. The compounds may find use as therapeutic agents for the treatment of diseases and may find particular use in oncology.
contain a 1,3-dihydro-2 H-indol-2-one (oxindole) skeleton. The binding of these compounds to the 5-HT 7 and 5-HT 1A receptors was measured. Despite the structural similarity of these two serotonin receptor subtypes, several derivatives exhibited a high selectivity to the 5-HT 7 receptor. According to the structure-activity relationship observations, compounds unsubstituted at the oxindole nitrogen atom
