A simple and efficient methodology for the direct halogenation of N -phenylureas was developed using trihaloisocyanuric acids in acetonitrile at room temperature. This protocol proved to be effective for the construction of N -phenylureas with different patterns of substitution. Additionally, less reactive N -benzylureas were halogenated in the presence of a mixture of trifluoroacetic acid and acetonitrile at room temperature.

Paragraph 0145-0148, (2016/11/17)
The invention discloses a method for synthesizing N,N'-disubstituent urea. The method comprises the following steps: adding N-substituent urea, a metal iridium, rhodium or ruthenium complex catalyst, an alkali, a compound alcohol and a solvent (or no solvent) to a reaction container; reacting at 90-130 DEG C for a plurality of hours and cooling the reaction mixture to room temperature; carrying out rotary evaporation to remove the solvent, and then separating through a column, so as to obtain a target compound. Compared with the prior art, N,N'-disubstituent urea which is obtained by regional selective alkylation reaction between commercial or easily synthesized N-substituent urea and the alcohol reflects and displays three significant advantages: 1) the alcohol which is nearly non-toxic is utilized as an alkylating reagent; 2) just water is generated as a by-product in the reaction, and harm to environment is not generated; 3) reaction atom economy is high. Therefore, the reaction accords with the requirements of green chemistry, and has a broad development prospect.

RhoA and its downstream effector ROCK mediate stress fiber formation and cell contraction through their effects on the phosphorylation of myosin light chain (MLC). Inhibition of the RhoA/ROCK pathway has proven to be a promising strategy for several indications such as cardiovascular disease, glaucoma, and inflammatory disease. In 2010, our group reported urea-based ROCK inhibitors as potential antiglaucoma agents. These compounds showed potent IC50 values in enzymatic and cell-based assays and significant intraocular pressure (IOP)-lowering effects in rats (~7 mmHg).(22) To develop more advanced ROCK inhibitors targeting various potential applications (such as myocardial infarction, erectile dysfunction, multiple sclerosis, etc.) in addition to glaucoma, a thorough SAR for this urea-based scaffold was studied. The detailed optimization process, counter-screening, and in vitro and in vivo DMPK studies are discussed. Potent and selective ROCK inhibitors with various in vivo pharmacokinetic properties were discovered.

A series of urea-based Rho kinase (ROCK) inhibitors were designed and evaluated. The discovered compounds had excellent enzyme and cellular potency, high kinase selectivity, high aqueous solubility, good porcine corneal penetration, and appropriate DMPK profiles for topical applications as antiglaucoma therapeutics.
