A Convenient Synthesis of 2‐(9H‐Fluoren‐9‐ylmethoxycarbonylamino)‐thiazole‐4‐carboxylic Acid via N‐Fmoc‐thiourea
摘要:
2-(9H-Fluoren-9-ylmethoxycarbonylamino)-thiazole-4-carboxylic acid has been prepared in high yield from 3-bromopyruvic acid and (aminothioxo-methyl)carbamic acid 9H-fluoren-9-ylmethyl ester (N-Fmoc-thiourea) that was obtained from potassium thiocyanate.
Aspects of the present invention include probes, methods, systems that have stand alone utility and may comprise features of a drug discovery system or method. The present invention also includes pharmaceutical compositions.
In more detail, the present invention provides molecular probes and methods for producing molecular probes. The present invention provides also provides systems and methods for new drug discovery. An embodiment of the present invention utilizes sets of probes of the present invention and a new approach to computational chemistry in a drug discovery method having increased focus in comparison to heretofore utilized combinatorial chemistry. The present invention also provides computer software and hardware tools useful in drug discovery systems. In an embodiment of a drug discovery method of the present invention in silico methods and in biologico screening methods are both utilized to maximize the probability of success while minimizing the time and number of wet laboratory steps necessary to achieve the success.
The present invention provides for novel compounds of Formulas I and II and pharmaceutically acceptable salts and co-crystals thereof which have glucokinsae activator activity. The present invention further provides for pharmaceutical compositions comprising the same as well as methods of treating, preventing, delaying the time to onset or reducing the risk for the development or progression of a disease or condition for which one or more glucokinase activator is indicated, including Type 1 and 2 diabetes, impaired glucose tolerance, insulin resistance and hyperglycemia. The present invention also provides for processes of making the compounds of Formulas I and II, including salts and co-crystals thereof, and pharmaceutical compositions comprising the same.
