What is medicinal chemistry and why is it important?
Medicinal chemistry is the branch of chemistry that deals with the discovery, design, synthesis, evaluation, and optimization of biologically active compounds for therapeutic use. It is also known as pharmaceutical chemistry or pharmacological chemistry. Medicinal chemistry combines aspects of organic chemistry, biochemistry, pharmacology, toxicology, and computer science to create new molecules that can modulate the function of biological targets such as enzymes, receptors, ion channels, or genes. Medicinal chemistry also involves studying the structure-activity relationship (SAR) of existing drugs and natural products to understand how their chemical structure affects their biological activity and pharmacokinetic properties.
Medicinal chemistry is important because it contributes to the development of new drugs that can treat various diseases and improve human health. According to the World Health Organization (WHO), there are still many unmet medical needs in the world, such as infectious diseases, cancer, diabetes, cardiovascular diseases, neurological disorders, and rare diseases. Medicinal chemistry plays a vital role in finding new solutions for these challenges by discovering new drug candidates that have novel mechanisms of action, higher potency, selectivity, safety, and efficacy than existing drugs. Medicinal chemistry also helps to optimize existing drugs by modifying their structure or formulation to enhance their bioavailability, stability, solubility, or reduce their side effects.
The scope and challenges of medicinal chemistry
Medicinal chemistry is a broad and interdisciplinary field that covers many aspects of drug discovery and development. Some of the main topics that medicinal chemists deal with are:
The sources and methods of drug discovery, such as natural products, synthetic compounds, combinatorial chemistry, high-throughput screening (HTS), computer-aided drug design (CADD), biotechnology, etc.
The design and synthesis of drug-like molecules that have desirable physicochemical properties (such as lipophilicity, polarity, acidity/basicity), biological properties (such as potency, selectivity, specificity), and pharmacokinetic properties (such as absorption, distribution, metabolism, excretion, or ADME).
The evaluation and optimization of drug candidates using various techniques and tools, such as in vitro assays, in vivo models, structure-based drug design (SBDD), ligand-based drug design (LBDD), quantitative structure-activity relationship (QSAR), pharmacophore modeling, molecular docking, etc.
The identification and characterization of biological targets and pathways that are involved in the pathogenesis of diseases or the modulation of physiological functions.
The understanding and prediction of the interactions between drugs and biological targets, such as binding affinity, mode of action, allosteric effects, etc.
The understanding and prediction of the interactions between drugs and other molecules in the body, such as enzymes, transporters, proteins, DNA, etc.
The understanding and prediction of the pharmacological effects and adverse effects of drugs in the body, such as efficacy, toxicity, drug-drug interactions, drug-food interactions, etc.
Medicinal chemistry is also a challenging field that faces many difficulties and limitations. Some of the main challenges that medicinal chemists face are:
The complexity and diversity of biological systems and diseases, which require a multidisciplinary approach and collaboration among different fields and disciplines.
The lack of reliable and relevant biological models and assays that can accurately reflect the human situation and predict the clinical outcomes.
The high cost and time-consuming process of drug discovery and development, which involve many stages and steps from target identification to clinical trials.
The low success rate and high attrition rate of drug candidates, which often fail due to poor efficacy, safety, or pharmacokinetics.
The increasing regulatory requirements and ethical standards that govern the drug discovery and development process.
The emergence of drug resistance and new diseases that pose new threats and challenges for drug discovery.
The drug discovery and development process
The drug discovery and development process is the sequence of steps that lead to the discovery and approval of new drugs for human use. It is a complex, lengthy, expensive, and risky process that involves many stages and steps from target identification to clinical trials. The following is a simplified overview of the main stages and steps of the drug discovery and development process:
Target identification: This is the first stage where a potential biological target (such as an enzyme, receptor, ion channel, or gene) that is involved in the pathogenesis of a disease or the modulation of a physiological function is identified and validated using various methods such as genomics, proteomics, metabolomics, etc.
Hit identification: This is the second stage where a large number of compounds (called hits) that can interact with the target are identified using various methods such as natural products screening, synthetic compounds screening, combinatorial chemistry screening, HTS screening, CADD screening, etc.
Hit-to-lead optimization: This is the third stage where the hits are evaluated and optimized using various criteria such as potency, selectivity, specificity, ADME properties, etc. The hits that meet these criteria are called leads.
Lead optimization: This is the fourth stage where the leads are further evaluated and optimized using more stringent criteria such as efficacy, toxicity, pharmacokinetics, etc. The leads that meet these criteria are called preclinical candidates.
Preclinical development: This is the fifth stage where the preclinical candidates are tested in vitro (in cell cultures or tissues) and in vivo (in animal models) to assess their pharmacological effects and adverse effects. The preclinical candidates that pass these tests are called clinical candidates.
Clinical development: This is the sixth stage where the clinical candidates are tested in humans to assess their safety, efficacy, and dosage. The clinical development consists of three phases: Phase I (testing in healthy volunteers), Phase II (testing in patients with the target disease), Phase III (testing in a large number of patients with the target disease). The clinical candidates that pass these phases are called new drug applications (NDAs).
Regulatory approval: This is the final stage where the NDAs are submitted to the regulatory authorities (such as the Food and Drug Administration or FDA in the US) for review and approval. The NDAs that are approved by the regulatory authorities are called new drugs or marketed drugs.
The drug discovery and development process can take from 10 to 15 years and cost from hundreds of millions to billions of dollars. Only a small fraction of drug candidates (about one in 10,000) make it to the market. Therefore, medicinal chemistry is a challenging but rewarding field that requires creativity, innovation, and perseverance.
