The secondary assays employed for lead selection may screen for off-target effects as well as physico-chemical and ADME (absorption, distribution, metabolism and excretion) characteristics. This WebElements periodic table page contains crystal structures for the element lead Rational Identification of Hsp90 Inhibitors as Anticancer Lead Molecules by Structure Based Drug Designing Approach. The research work will pave the way for the rational development of cost-effective Schiff bases as Hsp90 inhibitors as the method employed for the synthesis of the molecules is simple, economic and facile.

It is important to be able to predict and understand the molecular structure of a molecule because many of the properties of a substance are determined by its geometry. molecular structure: structure that includes only the placement of the atoms in the molecule octahedral: shape in which six outside groups are placed around a central atom such that a three-dimensional shape is generated with four groups forming a square and the other two forming the apex of two pyramids, one above and one below the square plane The findings come from the most detailed molecular analysis yet of the complex structure of concrete, which is a mixture of sand, gravel, water, and cement.

Lead (II) Azide is an inorganic compound that is largely used with explosive industries to produce detonators. The chemical formula for the compound is Pb (N3)2 and its molecular weight is 291.242 g mol-1 approx. It is formed by mixing lead cations and Azide anions together where nitrogen atoms are connected together with double bonds.
