1. Introduction

Through the selection and synthesis of compounds that establish structure activity connections and achieve efficacy and safety in preclinical animal testing, medicinal chemists play a critical role in the drug discovery process. Since the early days of drug discovery, when animal testing and small, informal project teams dominated the process, many facts of the medicinal chemist’s job have altered. The function of the chemist in the current period has evolved as a result of combinatorial chemistry, high throughput screening, and molecularly defined targets that permit structure based drug creation.

In particular, medicinal chemistry, which is most frequently used to study small organic molecules, includes synthetic organic chemistry, natural product related aspects, and computational chemistry in close collaboration with chemical biology, enzymology, and structural biology with the goal of discovering and creating novel therapeutics. In order to generate new chemical entities suitable for therapeutic use, it requires chemical aspects of identification followed by a systematic, complete synthetic change. It comprises studying existing medications and agents under development in regard to their bioactivities (biological activities and qualities), that is, understanding the links between Structure and Activity (SAR). Pharmaceutical chemistry is centred on the quality components of medications and works to ensure the medical goods are fit for their intended usage.

2. Description

At the biological interface, medicinal chemistry combines to form a group of highly interdisciplinary sciences, placing its organic, physical, and computational emphases alongside biological disciplines like biochemistry, molecular biology, pharmacognosy and pharmacology, toxicology, and veterinary and human medicine. These, along with project management, statistics, and pharmaceutical business practises, systematically oversee altering identified chemical agents so that after phasing out, the chemical agent no longer causes any adverse effects.

2.1. Discovery

Finding novel active chemical compounds, also known as “hits,” through the assessment of molecules for desired biological activity is the process of discovery. Initial successes can be attained by adapting currently used medicines to novel pathologic processes and by observing the biological effects of fresh or previously used natural materials derived from bacteria, fungus, plants, etc. In addition, structural observations of small molecule “fragments” bound to therapeutic targets (enzymes, receptors, etc.) frequently lead to hits. These fragments are then used as building blocks for the synthesis of more chemically complex forms. Hits frequently come from mass testing of chemical compounds against biological targets using biochemical or chemo proteomics assays. These compounds may come from recently synthesised chemical libraries known to have specific properties (kinase inhibitory activity, diversity, drug-likeness, etc.), or from older chemical compound collections or libraries developed through combinatorial chemistry. While there are many methods for finding and developing hits, the most effective ones are based on chemical and biological intuition that has been established in team settings via years of diligent practise that has been dedicated only to finding new therapeutic molecules.

Lead compounds: Lead compounds are substances that have therapeutic biological activity against a specific disease target. The hunt for new lead compounds is frequently a team effort that medicinal chemists direct with their knowledge and experience. The more compounds that are screened, the better the likelihood of success. Medicinal chemists search through enormous libraries of candidate compounds using either traditional combinatorial chemistry or computer modelling in silico approaches.

Compound synthesis: To produce new drug molecules and to re-synthesize screening hits for biological testing, medicinal chemists use synthetic techniques. However, change is on the horizon. Currently, medicinal chemists create molecules utilising established processes that produce structurally identical chemicals. Once they are created, these novel reactions will give medicinal chemists new options to synthesise a variety of molecules without having to waste time investigating novel reaction conditions.

Compound design: Medical chemists have a specialty in compound design, where they aid in balancing and combining the competing factors of biological function and structure.

Compound quality is a growingly important area of concern for the pharmaceutical industry, where declining clinical compound success rates are fuelling development attrition. For the advantage of medicinal chemists, industry research has led the path for more thorough design criteria, such as ligand efficiency and predictive models. To decrease late-stage attrition in drug development, medicinal chemists today frequently incorporate these characteristics and heuristics into compound design.

3. Conclusion

Discovering and selecting targets: Proteins, genes, and RNA are only a few examples of biological forms that might be referred to as targets. The chemical components of a drug target specific targets in order to have a therapeutic impact. These targets are associated with a disease process. The identification of safe, effective targets that are reachable by the medication molecule is guided by medicinal chemists.
