Norbornane is a bicyclic compound (bicyclo[2.2.1]heptane) with a rigid, saturated framework. Norbornene is its corresponding alkene, containing a double bond that makes it reactive toward typical electrophilic addition reactions. Norbornanone is a ketone derivative, where the carbonyl group undergoes nucleophilic … Read more
Tamoxifen is a selective estrogen receptor modulator (SERM) widely used in the treatment and prevention of estrogen receptor–positive breast cancer. Structurally, it is a triphenylethylene derivative, consisting of a substituted alkene framework connecting three aromatic rings, along with a basic side chain. … Read more
Ketamine is a dissociative anesthetic widely used in anesthesia and, more recently, in the treatment of depression. It belongs to a class of compounds characterized by an arylcyclohexanone framework, consisting of a substituted phenyl ring attached to a cyclohexanone ring … Read more
Diphenhydramine, best known under the brand name Benadryl, is a first-generation H₁ antihistamine widely used for the treatment of allergic conditions such as hay fever, urticaria, and other allergic reactions. It works by competitively blocking histamine H₁ receptors, thereby reducing … Read more
MDMA (3,4-methylenedioxymethamphetamine), commonly known as Ecstasy, is a synthetic psychoactive compound that combines stimulant and empathogenic effects. It was first synthesized in the early 20th century and later investigated for potential therapeutic uses, particularly in psychotherapy, before becoming widely … Read more
In today’s post, we will discuss the structures of some common Tropane Alkaloids, such as Atropine, Hyoscyamine, Scopolamine, and Cocaine. These naturally occurring compounds share the bicyclic tropane framework and play major roles in pharmacology, medicinal chemistry, and organic synthesis … Read more
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
Pethidine, also known as meperidine and marketed under the name Demerol, is a fully synthetic opioid of the phenylpiperidine class. Unlike morphine-based analgesics, its structure arises entirely from laboratory synthesis, making it a classic example of how multiple fundamental organic … Read more
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
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
