We designed and synthesized novel N-substituted 7-azaindoline derivatives as selective M1 and M4 muscarinic acetylcholine receptors (mAChRs) agonists. Hybridization of compound 2 with the HTS hit compound 5 followed by optimization of the N-substituents of 7-azaindoline led to identification of compound 1, which showed highly selective M1 and M4 mAChRs agonistic activity, weak human ether-a-go-go related
aprotic media yields superoxide anions O2.−. These highly reactiveradicalanions easily attack sensitive arenes. It is, therefore, not possible to generate the radicalanions of anthracene-9-carboxylic esters (1) by direct in situ electroreduction. Because derivatives substituted in the 10-position are stable against these radicals, indirect generation of the radicalanion 1.− was realized in order to
The present invention relates to substituted hydroxyureas. These compounds inhibit the enzyme 5-lipoxygenase. In addition, certain of the compounds also inhibit the enzyme-cyclooxygenase. The compounds are useful for treating asthma, allergies, arthritis, posoriasis, ischemia, dermatitis, inflammation and/or broncho-constriction and/or inflammatory diseases of the eye.
The new pyridine, 4‐pyridine N‐oxide and pyrazine derivatives exhibiting an antibacterial activity have been synthesized. Amidoximes were transformed into N‐hydroxyimidoyl chlorides and then into appropriate oximes. Upon treatment of pyridinecaboxamidoximes with methyl iodide 1‐methylpyridynium iodides were formed. Reaction of amidoximes with various carbamoyl chlorides led to corresponding 5‐aminocarbonyl‐1
Compounds of formula (I), wherein G represents together with the two carbon atoms of the pyrimidine ring to which it is attached, a 5- to 7-membered aliphatic carbocyclic or heterocyclic ring system which contain 0 to 2 heteroatoms selected from the group consisting of nitrogen, oxygen and sulfur; and wherein said 5- to 7-membered aliphatic carbocyclic or heterocyclic ring system can be mono-, di- or trisubstituted by substituents selected from the group consisting of halogen, keto, C1-C6alkyl, C1-C6alkoxy, C1-C6alkyloximino and C1-C6alkylendioxy; and wherein the other substituents R1, R2, R3, R4, R5 and R6 are as defined in claim 1, and their use as microbicides.
