Application of sulfur-containing isocyanate compounds in growth inhibition of blue-green algae
-
Paragraph 0042-0048; 0059-0063, (2020/04/29)
The invention relates to the application of sulfur-containing isocyanate compounds in the growth inhibition of blue-green algae. The compounds have structures as shown in a general formula I and a general formula II. In the general formula I, R1 represents a methyl group, a phenethyl group, a phenyl group, 4-methylpyridine or 3-methylpyridine. In the general formula II, M represents a carbonyl group, a methylene group and a methylene phenyl group; R3 represents hydrogen or chlorine; R4 represents oxygen, hydrogen, fluorine or chlorine; R5 represents oxygen, hydrogen, chlorine, a methyl group,fluorine, a benzene ring, bromine or a trifluoromethyl group; when R4 and R5 are oxygen, R4 and R5 are cyclized to form 1,3-dioxocyclopentene; R6 represents hydrogen, fluorine, bromine, a trifluoromethyl group, a methyl group and chlorine; and R7 represents hydrogen, a trifluoromethyl group, chlorine and bromine. The sulfur-containing isocyanate compounds with the structures as shown in the general formulas I and II provided by the invention have relatively good inhibition effect on blue-green algae, and can be used as an effective component of a blue-green algae algicide.

The serine protease urokinase (uPa) has been implicated in the progression of both breast and prostate cancer. Utilizing structure based design, the synthesis of a series of substituted 4-[2-amino-1,3-thiazolyl]-thiophene-2-carboxamidines is described. Further optimization of this series by substitution of the terminal amine yielded urokinase inhibitors with excellent activities.

2-(Substituted benzylamino)-2-thiazolines (SBAT) were synthesized by a hydrochloric acid-catalyzed cyclization of the corresponding thioureas, using a reaction of 2-methylthio-2-thiazoline with substituted benzylamines or by alkylating 2-amino-2-thiazoline. 2-(Alkylthio)-2-thiazolines were obtained by alkylating 2-mercaptothiazoline.Most of the SBAT compounds activated adenylate cyclase in homogenates of cockroach ventral nerve cords; the effect of introducing substituents at the phenyl of the SBAT compounds on octopaminergic agonist activity was not significant. 2--2-thiazolines and 2-(alkylthio)-2-thiazolines were not significant octopaminergic agonists.Washing removed nearly all of the activity of one of the SBAT compounds, suggesting that the SBAT compounds bound reversibly to the octopaminergic receptor.
