Synthesis of new 4-aryl-isoxazolo[5,4-d]pyrimidin-6-one(thione) and 4-aryl-pyrazolo[3,4-d]-pyrimidin-6-one derivatives of potential antihypertensive activity
Some aromatic aldehydes are subjected to react with urea (or thiourea) and acetyl acetone in a one-pot Biginelli-type cyclocondensation reaction to give 5-acetyl-4-aryl-6-methyl-1,2,3,4-tetrahydro-pyrimidines 2a-j. Aldehydes with ortho-hydroxy substituent namely salicylaldehyde and 2-hydroxy-3-methoxybenzaldehyde undergo Michael-type addition of the hydroxyl-proton to the C5−C6 double bond of t...
متن کاملSome heterocyclic thione derivatives exhibit anticoccidial activity by inhibiting glycosidases.
Coccidiosis is one of the most common parasitic diseases affecting many species of domestic animals. This disease has a major economic significance and the search for new compounds having anticoccidial activity is of great importance. In this article, different levels of protection from coccidian infection by Eimeria stiedae were developed in rabbits by treatment with compounds incorporating th...
متن کاملA Research on Synthesis of Oxazine Derivatives & Screening of Oxazine Derivatives for Certain Pharmacological Activities
Oxazine derivatives are an important class of heterocycles, which has attracted much synthetic interest due to their wide range of biological activities. Oxazine is a heterocyclic compound can be formally derived from benzene, and its reduction products, by suitable substitution of carbon (and hydrogen) atoms by nitrogen and oxygen. In the last few years oxazine derivatives have proved to be va...
متن کاملPiperidine derivatives; 1,3-dialkyl-4-aryl-4-acyloxypiperidines.
high analgesic potency, which, although in some instances exceeding that of morphine, does not reach that of dihydrodesoxymorphine-D. This latter has been shown to be 5 to 10 times 8;3 active as morphine (2). It could therefore be reversely postulated that the fragment of dihydrodesoxymorphine-D structure responsible for its high activity is that indicated by the heavy solid and possibly the br...
متن کاملHammett correlations in the chemistry of 3-phenylpropyl radicals.
The energetics and kinetics of the reaction of variously substituted benzyl radicals with a model alkene were calculated at the G3(MP2)-RAD//B3-LYP/6-31G(d) level of theory to determine whether such reactions are amenable to Hammett analysis. The reactions were studied both in the gas phase and in toluene solution in the temperature range 298-353 K; calculations include 1D-hindered rotor correc...
