<p>The present invention relates to novel 3-substituted (7-imino-2-thioxo-3, 7-dihydro-2H-thiazolo [4,5-d] pyrimidin-6-yl of formula 1 wherein R is selected from a group consisting of hydrogen, alkyl having carbon no up to 10, allyl, cycloalkyl, aromatic, substituted aromatics (halogen, OH, COOH, OCH3, alkyl, etc), pyridyl, piperidine, piprazine, morphine. R1 is selected from a group consisting of NH2, NHR, N(R) 2(wherein R could be aliphatic or olefinic group up to 10 carbon), hetrocycles such as furan, thiophene, pyrole, prydyl, piprazine, morphine and R2 is O and S separately. Particularly the present invention relates to (7-Imino-3-substituated -2-thioxo-3,7-dihydro-2H-thiazolo[4,5- d]pyrimidin-6-yl)-urea( 15-21) and Furan-2-carboxylic acid (7-imino-3 -substituted -2-thioxo-3,7- dihydro-2H-thiazolo[4,5-d]pyrimidin-6-yl)-amide. The compounds of present invention are useful in the treatment of central nervous disorders including, Parkinson disease, Huntington's disease, attention disorder, cognition, Alzheimer disease, depression and hypertension.</p> |
