For example, adriamycin was shown to be a DNA binding agent for many years.
But, polymeric conjugates of adriamycin exert anticancer activity without entering into the cell nucleus Tritton and Yee, ; Tritton, It was found that the drug-conjugate was located at the cell membrane and adriamycin was still bound to the polymer. Our research group has been involved in the development of new anticancer agents which have not been explored systematically 1.
Our endeavor in this area has not been smooth and problem free because we have used polyaromatic amine derivatives as key components in our molecules.
The main criticisms were that these molecules could generate mutagenicity in the cell. Extensive research has confirmed that certain polycyclic aromatic compounds are mutagenic and carcinogenic.
Does this mean that all polycyclic aromatic compounds are mutagenic? Numerous anthracyclines, metal-containing molecules, and mustards are presently in clinical use. In some examples, the activity has exceeded that of cisplatin, a well-known anticancer drug. Despite an enormous body of work that describes the cellular reaction of polycyclic aromatic hydrocarbon PAH , the application of these derivatives as anticancer agents has not been explored systematically.
Our work in this area has culminated in the synthesis of a large number of planar molecules using highly lipophilic polycyclic aromatic amines as the nucleus for a systematic examination of modifications of structures that might result in selective interactions with cancer cells.
This study has established lead compounds that are very effective against a variety of cancer cell lines. From structure-activity and in vitro and in vivo studies, lead compounds that are highly potent in HT human colon and SKOV-3 human ovarian cell lines have been developed. They were shown to produce selective apoptosis in HL cell lines. Although the major focus of therapeutic studies in cancer chemotherapy has been alterations of DNA replicative and repair functions, our studies have suggested that interactions with cell membranes may also play an important role in anticancer effectiveness1 Becker and Banik, ; Becker et al.
These explorations have taught me numerous lessons which I would like to share with. Unless we recruit dedicated and creative students, postdoctoral fellows and scientists in tackling some of the most challenging problems, there will be no progress made. Creativity does not really depend on the age although it has some influence on experience.
In science classes the understanding of concepts and the ability to solve problems should be emphasized over memorization. Students should be encouraged to develop their own problem-solving strategies.
Thus, problem solving is crucial in learning and practicing science. A researcher has to emphasize that research does not always proceed the way it is planned and that it is crucial to identify all the possibilities. This may turn out that the undesired products are more crucial than what we wanted to prepare.
During the course of our investigation, we have not obtained results predicted by many significant researchers. It was difficult to convince the scientific community some of the unprecedented science. However, appropriate support from experiments, instrumental work, and evidences have greatly facilitate our research.

The official guide By Lucy T. This involves the optimization of the synthetic route for bulk industrial production, and discovery of the most suitable drug formulation.
The former of these is still the bailiwick of medicinal chemistry, the latter brings in the specialization of formulation science with its components of physical and polymer chemistry and materials science.
The synthetic chemistry specialization in medicinal chemistry aimed at adaptation and optimization of the synthetic route for industrial scale syntheses of hundreds of kilograms or more is termed process synthesis , and involves thorough knowledge of acceptable synthetic practice in the context of large scale reactions reaction thermodynamics, economics, safety, etc.
Critical at this stage is the transition to more stringent GMP requirements for material sourcing, handling, and chemistry. Synthetic analysis[ edit ] The synthetic methodology employed in medicinal chemistry is subject to constraints that do not apply to traditional organic synthesis. Owing to the prospect of scaling the preparation, safety is of paramount importance. The potential toxicity of reagents affects methodology.
Lipinski's rule of five focus on the number of hydrogen bond donors and acceptors, number of rotatable bonds, surface area, and lipophilicity. Other parameters by which medicinal chemists assess or classify their compounds are: synthetic complexity, chirality, flatness, and aromatic ring count.
