Lead compounds Internet

After one or more lead compounds have been selected for further development, more preclinical investigations are needed before it is possible to start studies in humans. The main studies during this phase are toxicity studies in animals. It is important to note that the goal of these studies is not so much to find safe compounds and rejecf unsafe ones, but rather to learn under which conditions a potentially beneficial compound can be harmful, and to find out how it can be used safely in humans, if at all. Details on the type, duration and extent of toxicity studies needed can be found in various regulatory guidelines issued by ICH, FDA and EMEA and are easily accessible via the internet sites of these bodies. Although there are still differences in the requirements...

With a large data set of structures and properties, it is possible to use multivariate statistical methods such as principal components analysis to try to identify patterns. The applications of statistics to chemistry is known as chemometrics and an internet search for this keyword will lead to a variety of useful sources of information on the field. Some QSAR methods are based on the molecular orbitals of the compounds in the...
