Pharmacology is a bridge discipline between medicine and pharmacy,betmeen basic medicine and clinical medicine,between life sciences and chemistry as well as material science. Phar?macology is closely related to many subjects,and is an indispensable subject in medical sciences. It plays an important role in the development of medical sciences. The main tasks of pharmacology development involve rational drug use,new drug research and development,and promotion of medical sciences and life sciences. During the whole process of new drug development,the development of pharmacolo?gy has played a positive role. As such,new drug research and development depends on the develop?ment of pharmacology. Pharmacology plays an important role in the development of new drugs and is involved in the whole process of research and development. Thus,it is a support subject for new drug development. Strengthening pharmacological research and improving the overall level of pharmacologi?cal in China are of great significance for promoting new drug research and development and ensuring ra?tional drug use.

The development of new drug is not only the main driving force for the development of pharmaceutical industry, but also plays a very important role in the social development. However, with the increasing demands, new drug development is facing great difficulties in recent years. The hypothesis of highly selective single-target is meeting the challenges because of its limitations. Network pharmacology has been one of the new strategies for new drug discovery based on single-target drug research in recent years. This paper focused on the basis of network pharmacology and its research progress, discussed its development direction and application prospects, and analyzed its limitations and problems as well. The application of network pharmacology in new drug development is discussed by comparing its guidelines with those of traditional Chinese medicine theory and Effective Components Group hypothesis of Chinese medicines.

High-throughput screening is a regular approach available for identitying new lead compounds for the growing validated drug targets in drug screening. However, it has also introduced a large number of peculiar molecules which interfere drug screening. Pan assay interference compounds (PAINS) interfere with the progress of drug screening in various ways, such as interfering with a biochemical assay, modifying the protein, aggregate-based inhibitors and so on. So it is of vital significance to remove them. This paper has consulted the concept, category of PAINS and reviewed the way of PAINS interfering and the countermeasures to cope with them to direct the approach of high through screening and improve the hits percent.

Neurodegenerative diseases are complex nervous system disorders as a result of myelin damage,synapses loss and/ or neuron loss. The pathogenesis of these diseases is still not completely clear. Protein kinases play an important role in both normal nerve cells and neurodegenerative disorders. lnhibitors of protein kinases can effectively regulate the physiological function of nerve cells and prevent the development and progression of the disease. This article reviews protein kinases and their inhibitors involved in Alzheimer disease,Parkinson disease,Huntington disease and other neurodegenerative diseases.

This study discussed problems in consistency assessment of generic drugs and analyzed effect of polymorphs on drug quality and its influence on consistency of curative efficiency.Relationship between evaluation method of polymorphs and curative efficiency was investigated.It showed that establishment of curative efficiency related evaluation indicators was necessary and improvment of techniques was important.Drug quality criteria should be added with requirement of curative efficiency control.Related information based on polymorphs could be provided for technical research in consistency assessment.

PKC plays a pivotal role in the mechanism of myocardial preconditioning. After preconditioning, PKC is activated and translocated to membranes and cytoskeleton structures by multiple endogenous substances such as adenosine, calcium, etc. Recent studies imply that MAPK carries the signal from PKC to the mitochondria K ATP channel and thus protect the heart.

Advanced Glycation End products (AGEs) are the products of non enzymatic glycationprotein. It has been demonstrated that AGEs are closely correlated to a variety of diseases such as diabetes,vascular complications,aging and renal diseases. AGEs play important roles in the development of these diseases. They can effect the function of cells and tissues directly, and also mediate pathological reactions through binding with special receptors. The present paper reviews the procedures of AGEs production,action mechanism and pathology of AGEs.

Phosphodiesterases(PDEs) is the only protein enzyme family,which catalyze the hydrolysis of cyclic nucleotide second messages(cAMP and cGMP).PDEs regulate many physiologic and pathologic processes.Recent advance showed that PDE7 hydrolyze cAMP exclusively and is divided into PDE7A and PDE7B. PDE7 mainly express in immune and inflammatory cells.The selective inhibition of this family generates profound,functional effects and PDE7 has been used as a therapeutic target for diseases related with inflammation,such as chronic obstructive pulmonary disease(COPD),rheumatoid arthritis and Alzheimers disease(AD).

cAMP response element binding protein(CREB) is a genetranscription regulator locating in the nucleus.The activated CREB by phosphoration plays an important role by binding to the cAMP response elements and modulate the transcription of various target genes.In addition,the activity of CREB is also regulated by lots of transcriptional regulators in signal transduction mechanism.In central nerve system,CREB participates in promoting neuron growth,the processes of plasticity and long term memory.More importantly,researches of CREB in the pathological processes of Alzheimers disease,Hungtingtons disease and HIV-related dementia have made a progress recently,providing a basis for some therapy strategies to the related neurodegenerative disorders.
