- Application of sulfur-containing isocyanate compounds in growth inhibition of blue-green algae
-
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.

- Discovery and optimization of 4-oxo-2-thioxo-thiazolidinones as NOD-like receptor (NLR) family, pyrin domain-containing protein 3 (NLRP3) inhibitors
-
Aberrant activation of NLRP3 inflammasome is present in a subset of acute and chronic inflammatory diseases. The NLRP3 inflammasome has been recognized as an attractive therapeutic target for developing novel and specific anti-inflammatory inhibitors. Cellular structure-activity relationship-guided optimization resulted in the identification of 4-oxo-2-thioxo-thiazolidinone derivative 9 as a selective and direct small-molecule inhibitor of NLRP3 with IC50 of 2.4 μM, possessing favorable ex vivo and in vivo pharmacokinetic properties. Compound 9 may represent a lead for the development of anti-inflammatory therapeutics for treating NLRP3-driven diseases.

- Differentiating Antiproliferative and Chemopreventive Modes of Activity for Electron-Deficient Aryl Isothiocyanates against Human MCF-7 Cells
-
The consumption of Brassica vegetables provides beneficial effects through organic isothiocyanates (ITCs), products of the enzymatic hydrolysis of glucosinolate secondary metabolites. The ITC l-sulforaphane (l-SFN) is the principle agent in broccoli that demonstrates several modes of anticancer action. While the anticancer properties of ITCs like l-SFN have been extensively studied and l-SFN has been the subject of multiple human clinical trials, the scope of this work has largely been limited to those derivatives found in nature. Previous studies have demonstrated that structural changes in an ITC can lead to marked differences in a compound's potency to 1) inhibit the growth of cancer cells, and 2) alter cellular transcriptional profiles. This study describes the preparation of a library of non-natural aryl ITCs and the development of a bifurcated screening approach to evaluate the dose- and time-dependence on antiproliferative and chemopreventive properties against human MCF-7 breast cancer cells. Antiproliferative effects were evaluated using a commercial MTS cell viability assay. Chemopreventive properties were evaluated using an antioxidant response element (ARE)-promoted luciferase reporter assay. The results of this study have led to the identification of 1) several key structure–activity relationships and 2) lead ITCs for continued development.

- Microwave Assisted Synthesis of Trifluoro Substituted 2-Aminobenzimidazole Derivatives via Iodoacetic Acid Mediated One-pot Condensation
-
Microwave-assisted efficient one-pot syntheses of trifluoro substituted 2-aminobenzimidazole derivative were synthesized using iodoacetic acid mediated cyclodesulfurization of thioureas. This method eliminates need to handle preformed substituted thioureas, requires lesser reaction time and temperature, is facile, and also gives higher yields of the target molecules.

- Synthesis and Octopaminergic Agonist Activity of 2-(Substituted benzylamino)-2-thiazolines
-
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.
