摘要:
The invention relates to a novel method for producing N-methyl-N'-nitroguanidine by reacting nitroguanidine with an aqueous methylamine solution that has been buffered by adding inorganic or organic acids.
摘要:
Guanidine substituted arginines or homoarginines based on monoalkyl carbon substituted ornithines or lysines, having formula (I) wherein R is (CH2)yCH3 or H, R' is CH2 or C(H)(CH2)yCH3, and R" is CH2 or C(H)(CH2)yCH3, with y ranging from 0 to 5, and x is 0 or 1 and Q is an alkyl group containing from 1 to 6 carbon atoms or NH2 or NO2, and only one of R, R' and R" providing an alkyl substituent on the ornithine or lysine moiety. A composition includes said compound together with a pharmaceutically acceptable carrier. Methods of use are directed to delivering said compound to inducible nitric oxide synthase to inhibit the ability of the enzyme to catalyze the conversion of arginine to nitric oxide, to administering said compound to inhibit pathological overproduction of nitric oxide from arginine and to administering said compound to a subject having systemic hypotension due to the pathological overproduction of nitric oxide and an alpha 1, adrenergic agonist to increase blood pressure in the subject to a clinically acceptable level.

摘要:
An insecticidal composition containing a guanidine derivative of the formula:
wherein R¹ is an optionally substituted homocyclic or heterocyclic group, n is 0 or 1, R² is a hydrogen atom or an optionally substituted hydrocarbon group, R³ is a primary, secondary or tertiary amino group, X is an electron attractive group such as nitro or trifluoroacetyl group, provided that when n is 0, R¹ is an optionally substituted heterocyclic group or a salt thereof.
摘要:
The present invention discloses hydrocarbylidene nitrohydrozinecarboximidamides and the use thereof as well as a method for making the same. The structural general formula of the compounds are shown in formula I, wherein, R1 is C1 - C10 saturated and/or unsaturated aliphatic hydrocarbonyl, benzyl, substituted benzyl, halogenated picolyl, halogenated thiazolyl methyl, tetrahydrofuryl methyl or oxazolyl methyl; R2 is hydrogen, C1 - C5 saturated and/or unsaturated aliphatic hydrocarbonyl, phenyl, substituted phenyl, pyridyl or substituted pyridyl; R3 is hydrogen, C1 - C10 saturated and/or unsaturated aliphatic hydrocarbonyl, furyl, phenyl, substituted phenyl, benzyl or substituted benzyl. The tests of insecticidal activity show that the hydrocarbylidene nitrohydrozinecarboximidamides shown by formula (I) have high preventive efficiency against insect pests of plants, such as aphid, plant hopper, cotton bollworm, asparagus caterpillar, and the like, and can be used as plant insecticides.
