NOVEL CYSTOBACTAMIDE DERIVATIVES

The present invention relates to novel derivatives of cystobactamides of formula (lb) and the use thereof for the treatment or prophylaxis of bacterial infections.

A practically simple, catalyst free and scalable synthesis of: N -substituted ureas in water

A practically simple, mild and efficient method is developed for the synthesis of N-substituted ureas by nucleophilic addition of amines to potassium isocyanate in water without organic co-solvent. Using this methodology, a variety of N-substituted ureas (mono-, di- and cyclic-) were synthesized in good to excellent yields with high chemical purity by applying simple filtration or routine extraction procedures avoiding silica gel purification. The developed methodology was also found to be suitable for gram scale synthesis of molecules having commercial application in large volumes. The identified reaction conditions were found to promote a unique substrate selectivity from a mixture of two amines.

Conventional and Microwave-Activated the Synthesis of a Novel Series of Imidazoles, Pyrimidines, and Thiazoles Candidates

A novel series of imidazoles, pyrimidines, and thiazoles were synthesized using microwave irradiation and conventional method from commercial available p-aminobenzoic acid. Thus, one-pot condensation of p-aminobenzoic acid, urea, and chloroacetic acid have been provided two types of imidazole derivatives as separated mixture 2a and 2b. [3?+?2?+?1] Cyclocondensation of 2a, benzaldehyde, and urea/thiourea in acidic medium afforded imidazolo oxazine derivative 3 and Imidazolothiazine 4. Coupling of 2a with benzene diazonium salt gave the phenyldiazenyl imidazolidine 5. While the reaction of 2a, thiourea, and benzaldehyde in sodium ethoxide afforded imidazolothiazine 6. Oxidative cyclization of thiourea derivative 7 resulted a mixture of benzithiazole derivative 7a and oxathiazole derivative 7b. Cyclocondensation of 7a with phenylenediamine and 4-methyl phenylenediamine furnished imidazole 8 and 9, respectively. Reaction of P-aminobenzioc acid with potassium cyanate followed by Biginelli reaction with (acetyl acetone, ethyl acetoacetate, and diethyl malonate) and salicyladehyde in HCl tolerated pyrimidine derivatives 10a–c, respectively. In the same manner, the reactions and short reaction time make microwave technique one of the greenest methodology for synthesis of this class of heterocyclic system.

ANTI-PCSK9 COMPOUNDS AND METHODS FOR THE TREATMENT AND/OR PREVENTION OF CARDIOVASCULAR DISEASES

Disclosed are compounds that modulate the physiological action of the proprotein convertase subtilisin kexin type 9 (PCSK9), and methods of using these modulators to reduce LDL-cholesterol levels and/or for the treatment and/or prevention of cardiovascular disease (CVD), including treatment of hypercholesterolemia.

Synthesis and biological activity evaluation of novel imidazolidinedione derivatives, as potent antidiabetic agent

A set of novel imidazolidinedione derivatives were synthesized and evaluated as potential antidiabetic agents. Imidazolidinedione scaffold-based molecules were synthesized and validated on a mice hyperglycemia model caused by alloxan. As a result, three of them showed antihyperglycemic activities. This research provides useful clues for further design and discovery of antidiabetic agents.
