Bioorganic chemistry plays a crucial role in elucidating the molecular mechanisms underlying various biological processes, including enzyme catalysis, signal transduction, drug interactions, and molecular recognition (Xinkuan et al., 2016).
In drug design and discovery, diverse computational chemistry approaches are used to calculate and predict events, such as the drug binding to its target and the chemical properties for designing potential new drugs.

The Laboratory of Bioorganic Chemistry (LBC) explores biomedical problems at the interface of chemistry and biology. Founded by the late John Daly in 1978, LBC has a rich history of chemical research that includes organic synthesis, medicinal chemistry, natural products chemistry, structural biology and pharmacology.
Key themes include the discovery, design or optimization of potent new compounds, the discussion of structure-activity relationships and
This special issue at the interface between chemistry and biology will cover the fields of bioorganic and medicinal chemistry with a focus
Are drug discovery teams organized in a multidisciplinary way?
However, they are rarely organized (nor is it their mission) to embrace the drug discovery process in the multidisciplinary fashion outlined above that is the modern paradigm by which new hits or leads are first identified and then get transformed into new viable medicines.
How does synthetic chemistry affect drug development?
Synthetic chemistry has a major impact on the drug development process because it provides new molecules for future study. Natural products based semisynthesis or microwave assisted synthesis is also involved in developing newly designed drug molecules.
What is the role of analytical chemistry in drug development?
Natural products based semisynthesis or microwave assisted synthesis is also involved in developing newly designed drug molecules. Further, the role of analytical chemistry involves extraction, fractionation, isolation and characterization of newly synthesized molecules.
What role does organic chemistry play in drug discovery?
The role played by organic chemistry in the pharmaceutical industry continues to be one of the main drivers in the drug discovery process. However, the precise nature of that role is undergoing a visible change, not only because of the new ..
Selective serotonin reuptake inhibitors, or serotonin-specific re-uptake inhibitor (SSRIs), are a class of chemical compounds that have contributed to the major advances as antidepressants where they have revolutionised the treatment of depression and other psychiatric disorders. The SSRIs are therapeutically useful in the treatment of panic disorder (PD), posttraumatic stress disorder (PTSD), social anxiety disorder, obsessive-compulsive disorder (OCD), premenstrual dysphoric disorder (PMDD), and anorexia. There is also clinical evidence of SSRIs efficiency in the treatment of the negative symptoms of schizophrenia and their ability to prevent cardiovascular diseases.
The discovery of an orally inactive peptide from snake venom established the important role of angiotensin converting enzyme (ACE) inhibitors in regulating blood pressure. This led to the development of captopril, the first ACE inhibitor. When the adverse effects of captopril became apparent new derivates were designed. Then after the discovery of two active sites of ACE: N-domain and C-domain, the development of domain-specific ACE inhibitors began.
Cyclooxygenases are enzymes that take part in a complex biosynthetic cascade that results in the conversion of polyunsaturated fatty acids to prostaglandins and thromboxane(s). Their main role is to catalyze the transformation of arachidonic acid into the intermediate prostaglandin H2, which is the precursor of a variety of prostanoids with diverse and potent biological actions. Cyclooxygenases have two main isoforms that are called COX-1 and COX-2. COX-1 is responsible for the synthesis of prostaglandin and thromboxane in many types of cells, including the gastro-intestinal tract and blood platelets. COX-2 plays a major role in prostaglandin biosynthesis in inflammatory cells and in the central nervous system. Prostaglandin synthesis in these sites is a key factor in the development of inflammation and hyperalgesia. COX-2 inhibitors have analgesic and anti-inflammatory activity by blocking the transformation of arachidonic acid into prostaglandin H2 selectively.
Dipeptidyl peptidase-4 inhibitors are enzyme inhibitors that inhibit the enzyme dipeptidyl peptidase-4 (DPP-4). They are used in the treatment of type 2 diabetes mellitus. Inhibition of the DPP-4 enzyme prolongs and enhances the activity of incretins that play an important role in insulin secretion and blood glucose control regulation. Type 2 diabetes mellitus is a chronic metabolic disease that results from inability of the β-cells in the pancreas to secrete sufficient amounts of insulin to meet the body's needs. Insulin resistance and increased hepatic glucose production can also play a role by increasing the body's demand for insulin. Current treatments, other than insulin supplementation, are sometimes not sufficient to achieve control and may cause undesirable side effects, such as weight gain and hypoglycemia. In recent years, new drugs have been developed, based on continuing research into the mechanism of insulin production and regulation of the metabolism of sugar in the body. The enzyme DPP-4 has been found to play a significant role.
Gliflozins are a class of drugs in the treatment of type 2 diabetes (T2D). They act by inhibiting sodium/glucose cotransporter 2 (SGLT-2), and are therefore also called SGLT-2 inhibitors. The efficacy of the drug is dependent on renal excretion and prevents glucose from going into blood circulation by promoting glucosuria. The mechanism of action is insulin independent.

Class of immunomodulatory drugs
Immunomodulatory imide drugs (IMiDs) are a class of immunomodulatory drugs containing an imide group. The IMiD class includes thalidomide and its analogues. These drugs may also be referred to as 'Cereblon modulators'. Cereblon (CRBN) is the protein targeted by this class of drugs.
LBP-1 is a drug originally developed by Organon for the treatment
Chemical compound
LBP-1 is a drug originally developed by Organon for the treatment of neuropathic pain, It acts as a potent and selective cannabinoid receptor agonist, with high potency at both the CB1 and CB2 receptors, but low penetration of the blood–brain barrier. This makes LBP-1 peripherally selective, and while it was effective in animal models of neuropathic pain and allodynia, it did not produce cannabinoid-appropriate responding suggestive of central effects, at any dose tested.
