It belongs to a class of drugs known as second-generation antipsychotics, which act primarily by modulating dopamine (D₂) … Read more

Synthesis of Primidone

Primidone is an anticonvulsant (antiepileptic) medication used primarily to treat seizure disorders, including generalized tonic-clonic and partial seizures. Chemically, it is a barbiturate-related compound (a deoxybarbiturate), meaning it is structurally similar to barbiturates but has a slightly different pharmacological profile. … Read more

Synthesis of Medazepam

Medazepam

Medazepam is a benzodiazepine derivative used for its anxiolytic, anticonvulsant, sedative, and skeletal muscle relaxant properties. It has been marketed in various countries under several brand names, including Azepamid, Nobrium, Tranquirax (when combined with bevonium), Rudotel, Raporan, Ansilan, and Mezapam. … Read more

Synthesis of Loperamide

Loperamide is an antidiarrheal medication best known under the brand name Imodium. It works by activating μ-opioid receptors in the intestinal tract, which slows down gut movement and reduces the frequency of bowel movements. Unlike other opioids, Loperamide does not … Read more

Synthesis of Sulfanilamide

Sulfanilamide, one of the earliest synthetic antimicrobial agents, holds a foundational place in medicinal chemistry because it introduced the concept of selectively inhibiting bacterial metabolism. As a member of the sulfonamide class, its structure mimics p-aminobenzoic acid (PABA), allowing it … Read more

Synthesis of Lidocaine

Lidocaine is a widely used local anesthetic and antiarrhythmic drug that works by blocking voltage-gated sodium channels, preventing nerve signal transmission. Its structure contains both an aromatic amide and a tertiary amine side chain, making it an excellent example of … Read more

Synthesis of Ibuprofen

Ibuprofen, the active ingredient in brands such as Advil, is a widely used non-steroidal anti-inflammatory drug (NSAID) that reduces pain, fever, and inflammation by inhibiting the cyclooxygenase (COX) enzymes responsible for prostaglandin synthesis. It is one of the most common … Read more

Synthesis of Prozac (Fluoxetine)

Fluoxetine (Prozac)

Prozac (Fluoxetine) is a widely used antidepressant belonging to the class of selective serotonin reuptake inhibitors (SSRIs). It increases serotonin levels in the brain by inhibiting its reabsorption, which helps improve mood and treat depression, anxiety disorders, and OCD.   … Read more

Synthesis and Reactions of Lactones and Lactams

Lactones through Intramolecular Fischer esterification

In this post, we will discuss and show the mechanisms of some important reactions of lactones and lactams, such as their preparation, acid- and base-catalyzed hydrolysis, and reduction by LiAlH4. We will also go over the Grignard reaction of lactones. … Read more
