First, a chemical compound is represented by a feature vector which counts frequencies of substructure occurrences in the structural formula. Second, an enzyme reaction is represented as an operator vector by detecting the structural changes to compounds before and after the reaction. B...
For every chemical compound that has caused societal, environmental or health issues (asbestos, DDT, thalidomide, chlorofluorocarbons), there are dozens of others which have caused no harm or provided us with great benefits (penicillin, Kevlar, Nylon)....

(3-MC), polychlorobiphenyls, DDT, and benzo(a)pyrene. The inducers may lower the toxicity of other chemicals by accelerating theirdetoxication. For example, pretreatment with phenobarbital shortens the sleeping time induced byhexobarbitaland the paralysis induced byzoxazolamine. In addition, 3-MC...
The preferred method for making DDTBP is that described by Ueda et al. (Macromolecules 1988, 21 19-24) except that toluene is used instead of benzene. 2) Preferred Polyamic Acids The preferred polyamic acids have the general formula (3): ##STR3## wherein R is a tetravalent radical; R...
3. A compound according to claim 1 of formula (IIIA). Description: The present invention relates to novel phenyl pyrimidinone derivatives which have insecticidal activity, to processes for their preparation and to their use as insecticides.
The present invention (2) relates to the method for preparing the compounds, more particularly to the method for preparing the compounds of the general formula (I) in a high yield, ##EQU5## by reacting a sulfinylhalide of the general formula (II); ##EQU6## wherein R2 has the same ...
Suitably the compound of Formula (I) is not 3-[1-(phenylacetyl)-2,3-dihydro-1H-indol-5-yl]-7-(3-pyridinyl)thieno[3,2-c]pyridin-4-amine. For compounds of Formula (I), suitably R1 is bicycloheteroaryl substituted with from one to three substituents independently selected from: halo, ...
