1. Identification Summary Alcohol (functional group) denotes an sp³ carbon bearing a hydroxyl (–OH) substituent: general formula R–OH. Hallmarks: hydrogen bonding, moderate nucleophilicity of the oxygen lone pairs, weak Brønsted acidity (pKₐ ~15–19), and formation of derivatives (ethers, esters, sulfonates). Brand Names Not applicable. Name Alcohol (hydroxyl functional group) Background Classified by substitution at the … Read more
Introduction Antifungal drugs are pharmacological agents used to treat fungal infections (mycoses) affecting the skin, mucous membranes, or internal organs. Mechanism of Action of Antifungal Drugs involves disruption of fungal cell membrane integrity, cell wall synthesis, or nucleic acid function. Since fungal cells are eukaryotic and share many structural similarities with human cells, antifungal agents … Read more
1. Identification Summary Ketone is a carbonyl functional group in which the carbonyl carbon is bonded to two carbons (R₂C=O; neither R is H). The carbonyl is sp², trigonal planar, strongly electrophilic, and shows a characteristic C=O IR band near ~1715 cm⁻¹ for simple aliphatic ketones (conjugation/substitution shifts lower). α-Hydrogens adjacent to the carbonyl are … Read more
1. Identification Summary Carboxylic acid denotes the carboxyl (–C(=O)OH) functional group; general formula R–COOH. Core features: acidic proton on the hydroxyl, resonance-stabilized carboxylate conjugate base, strong hydrogen bonding, and broad derivatization (esters, amides, anhydrides, acid chlorides). Brand Names Not applicable. Name Carboxylic acid (carboxyl group) Background Ubiquitous in organic, medicinal, and biochemistry contexts (fatty acids, amino acids, many APIs). Electron-withdrawing substituents lower pKₐ; … Read more
1. Identification Summary Benzene is an aromatic hydrocarbon (C₆H₆) consisting of a planar six-membered ring with delocalized π electrons; a foundational motif (“phenyl”) in organic chemistry and an industrial solvent/intermediate. Brand Names Not applicable. Name Benzene Background Endogenous to crude oil and combustion streams; widely used as a chemical feedstock; environmental and occupational toxicant with … Read more
1. Identification Summary Azithromycin is a 15-membered azalide macrolide antibiotic indicated for susceptible infections across respiratory, skin/soft-tissue, sexually transmitted, and atypical pathogen settings; class cautions include QT prolongation/arrhythmia risk, hepatotoxicity, C. difficile–associated diarrhea, and myasthenia gravis exacerbation. Brand Names Zithromax, Sumamed; multiple generics (region-dependent) Name Azithromycin Background Semisynthetic azalide derived from erythromycin A; oral, IV, … Read more
1. Identification Summary Losartan is an angiotensin II receptor blocker (ARB) for hypertension, diabetic nephropathy in type 2 diabetes with proteinuria, and risk reduction of stroke in hypertensive patients with left ventricular hypertrophy. Brand Names Cozaar; numerous generics Name Losartan Background First-in-class ARB; marketed commonly as the potassium salt for oral tablets and fixed-dose combinations … Read more
1. Identification Summary Cholesterol is an endogenous sterol (cholest-5-en-3β-ol) essential for mammalian cell membranes, precursor of bile acids, steroid hormones, and vitamin D, and a major cargo of lipoproteins (HDL, LDL, VLDL). Brand Names Not applicable (endogenous biomolecule; bulk chemical/excipient). Name Cholesterol Background Core membrane lipid that modulates fluidity and raft microdomains; central node of … Read more
Introduction Antibiotics are chemotherapeutic agents used to kill or inhibit bacterial growth by targeting essential microbial functions that differ from those in human cells. Mechanism of Action of Antibiotics involves interference with bacterial cell wall synthesis, protein translation, DNA or RNA replication, metabolic pathways, or membrane integrity. These mechanisms ensure selective toxicity—destroying bacterial cells while … Read more
