The theory of hard and soft acids, bases, nucleophiles, and electrophiles is often confusing for students, so, as always, we’ll do our best to make it a little more approachable. Speaking of approachable, you may have noticed in yourself or … Read more
One of the first reactions of Grignard reagents we learn is the one with aldehydes and ketones, where secondary and tertiary alcohols are formed: These are classic examples of nucleophilic addition reactions to carbonyl compounds, and the good … Read more
Ritalin is a central nervous system stimulant used primarily in the treatment of attention-deficit/hyperactivity disorder (ADHD) and narcolepsy. It acts by increasing dopamine and norepinephrine levels in the brain through inhibition of their reuptake. Structurally, Ritalin contains a phenyl ring … Read more
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
Quetiapine is an atypical antipsychotic used in the treatment of schizophrenia, bipolar disorder, and as an adjunct in major depressive disorder. It works by modulating neurotransmitter systems, particularly dopamine and serotonin receptors. Structurally, quetiapine contains a dibenzothiazepine core connected to … Read more
Pioglitazone is an antidiabetic drug used in the treatment of type 2 diabetes. It belongs to the thiazolidinedione class and works by improving insulin sensitivity, helping to regulate blood glucose levels. Structurally, pioglitazone contains a thiazolidinedione core attached to an … Read more
Ezetimibe is a cholesterol absorption inhibitor used in the treatment of hyperlipidemia, which is a common, often asymptomatic condition characterized by high levels of lipids (cholesterol/triglycerides) in the blood, which can lead to plaque buildup in arteries. Structurally, it is … Read more
Fentanyl is a potent synthetic opioid widely used for pain management and anesthesia. Structurally, it is a phenylpiperidine derivative, featuring a substituted aniline ring, a piperidine heterocycle, and an amide linkage connecting the key fragments. Its biological activity arises from … Read more
Sertraline is a selective serotonin reuptake inhibitor (SSRI) widely used in the treatment of depression, anxiety disorders, and related conditions. Structurally, it is a substituted tetralin derivative, featuring a fused bicyclic aromatic system, a dichlorinated phenyl ring, and a secondary … Read more
Albuterol is a short-acting β2-adrenergic receptor agonist widely used in the treatment of asthma and other conditions involving bronchospasm. Structurally, it is a substituted phenethylamine derivative, featuring a resorcinol (1,3-dihydroxybenzene) ring, a β-hydroxylated side chain, and a tert-butyl-substituted amine. Its … Read more
