An important approach to the graphic representation of molecules is the use of a connection table. A connection table is a data base that stores the available bond types and hybridizations for individual atoms. Using the chemical formula and the connection table, molecular stmctures may be generated through interactive graphics in a menu-driven environment (31—33) or by using a linear input of code words (34,35). The connection table approach may be carried to the next step, computer-aided molecular design (CAMD) (36). 

This type of solvent selection problem can be formulated and solved as a Computer Aided Molecular Design (CAMD) problem [22], Application of this method for solvent selection and design is highlighted in chapter 14 and is not discussed in detail in this chapter. The ProCAMD software [23], which is based on a hybrid CAMD method can be used to solve solvent selection problems of this type. 

Computer aided molecular design (CAMD) problems are defined as, Given a set of building blocks and a specified set of target properties Determine the molecule or molecular structure that matches these properties. 

In another example, Chavali et al. demonstrated that 2D connectivity indices can give good structure/property correlations in molybdenum-catalyzed epoxidation [53,54]. They used the Computer Aided Molecular Design (CAMD) environment, a powerful computational tool used in product design. The method uses optimization techniques coupled with molecular design and property estimation methods, generating those molecular structures that match a desired set of properties. 

However, as there is no free DNA in the cell, and the real target for DNA-inter-active agents is the chromatin, it is not clear whether in vitro studies can contribute to understanding of cellular DNA sequence selectivity. Various synthetic approaches and mechanistic studies assisted by computer aided molecular design (CAMD) have been described aiming at an optimization of the pharmacological properties of the enediyne antibiotics [80]. It remains to be seen whether enediynes, either natural or designed, will become a useful supplement to the arsenal for the treatment of cancer. 

Structure-based molecular design, computer-aided molecular design (CAMD), computer-aided drug design (CADD), approaches for lead structure identification and optimization in the drug development process. The rational design of a lead structure in drug development basically relies upon the three-dimensional structure of... 

The initial motivation for the use of SAR was to empirically define and quantify the effects of steric, electronic, and lipophilic properties of substituents on biological activity. Not surprisingly, the retrospective success of early studies in predicting bioactivity attracted industrial attention, taking Computer-Aided Molecular Design (CAMD) out of the academic realm and into the pharmaceutical, agricultural, and polymer chemistry companies. 

Computer-Aided Molecular Design (CAMD) CAMD was developed by the Department of Chemical Engineering s Computer-Aided Process Engineering Centre at the Technical University of Denmark. CAMD can be used to select and design new solvents based on fliermodynamic properties. It contains a database wifli ftiousands of chemicals which can be accessed to select the desired chemical. If the chemical does not exist, CAMD uses computational chemistry to build the chemical configuration of flic new chemical. ... 

In principle, aU these aspects related with the solvent selection will have an impact on the outcome of the LCA metrics of the various alternatives. Fig. 13.2 presents a generic flowsheet for the solvent-based postcombustion CO2 capture processes, illustrating also the main concerns from an LCA point of view. If the LCA scope is to screen solvents for postcombustion CO2 capture without performing process simulations (i.e., in a very early phase of process design, where perhaps the number of solvent molecules to be screened is immense, for instance, in computer-aided molecular design [CAMD] of solvent molecules [68]), the potential solvents should be characterized based on properties that would indicate their expected performance in the capture process (e.g., the standard flowsheet of Fig. 13.2). These properties can be thermodynamic in nature (e.g., solubility parameters between CO2 and the solvent, solvent heat of vaporization.
