摘要:
The present invention relates to a process for the preparation of 5-(2-amino-pyrimidin-4-yl)-2-aryl-1H-pyrrole-3-carboxamides and to the useful intermediate compounds of such process. 5-(2-Amino-pyrimidin-4-yl)-2-aryl-1H-pyrrole-3-carboxamides are described and claimed in W02007110344, which also discloses processes for their preparation. These compounds can be advantageously prepared through a process which allows to obtain the desired products in high yields and purity and with a limited number of steps. The synthesis is starting from a cyano pyrrole derivative, and is characterized from the final hydrolysis of 5-(2-amino-pyrimidin-4-yl)-2-aryl-1H-pyrrole-3-carbonitrile. The compounds prepared according to the process of the present invention are endowed with protein kinase inhibiting activity and, more particularly, Cdc7 or Cdc7/Cdks inhibiting activity. The compounds are therefore useful in the treatment of a variety of cancers, cell proliferative disorders and diseases associated with protein kinases.

摘要:
A process for preparing 2-methyl substituted penems useful as antibiotics agent and/or as intermediates thereof, by reacting an appropriate 1-imido-3,4-disubstituted azetidinone derivative with a trivalent organophosphorus compound in an inert solvent at a temperature of from 110.degree. to 150.degree. C. for a period of from 2 hours to a few days.
摘要:
The present invention relates to peptides and peptidomimetic compounds and pharmaceutical compositions containing them as useful pharmacological agents in the control or treatment of proliferative diseases such as cancer, against tumor growing and/or tumoral metastasis, and psoriasis and in the control or treatment of inflammatory, allergic, autoimmune, viral, and cardiovascular diseases. These new compounds have the unique property to inhibit the recognition of several phosphotyrosine containing motifs within all the cellular receptors and cytosolic transducers by a wide spectrum of SH2 domains contained in cytosolic transducers and other effector proteins laying along different pathways of the signal transduction process and with a particularly high affinity for the SH2 domain of the adaptor transducer Grb2, a key element along the pathway to mitogenesis and motogenesis, this last activity leading to invasiveness and to metastasis. The invention also relates to methods for production of the compounds and methods of treatment employing the compounds.
