  2. Amide - Wikipedia

    en.wikipedia.org/wiki/Amide

    General structure of an amide (specifically, a carboxamide) Formamide, the simplest amide Asparagine (zwitterionic form), an amino acid with a side chain (highlighted) containing an amide group. In organic chemistry, an amide, [1] [2] [3] also known as an organic amide or a carboxamide, is a compound with the general formula R−C(=O)−NR′R ...

  3. Local anesthetic - Wikipedia

    en.wikipedia.org/wiki/Local_anesthetic

    Many local anesthetics fall into two general chemical classes, amino esters (top) and amino amides (bottom). A local anesthetic (LA) is a medication that causes absence of all sensation (including pain) in a specific body part without loss of consciousness, [1] providing local anesthesia, as opposed to a general anesthetic, which eliminates all sensation in the entire body and causes ...

  5. β-Lactam - Wikipedia

    en.wikipedia.org/wiki/Β-Lactam

    A lactam is a cyclic amide, and beta-lactams are named so because the nitrogen atom is attached to the β-carbon atom relative to the carbonyl. The simplest β-lactam possible is 2-azetidinone. β-lactams are significant structural units of medicines as manifested in many β-lactam antibiotics . [ 2 ]

  6. Ropivacaine - Wikipedia

    en.wikipedia.org/wiki/Ropivacaine

    Ropivacaine / r oʊ ˈ p ɪ v ə k eɪ n / is a local anaesthetic drug belonging to the amino amide group. The name ropivacaine refers to both the racemate and the marketed S-enantiomer. Ropivacaine hydrochloride is commonly marketed by AstraZeneca under the brand name Naropin.

  7. Amide (functional group) - Wikipedia

    en.wikipedia.org/wiki/Amide_(functional_group)

    Structures of three kinds of amides: an organic amide (carboxamide), a sulfonamide, and a phosphoramide. In chemistry, the term amide (/ ˈ æ m aɪ d / or / ˈ æ m ɪ d / or / ˈ eɪ m aɪ d /) [1] [2] [3] is a compound with the functional group R n E(=O) x NR 2, where x is not zero, E is some element, and each R represents an organic group or hydrogen.

  8. Nicotinamide - Wikipedia

    en.wikipedia.org/wiki/Nicotinamide

    The structure of nicotinamide consists of a pyridine ring to which a primary amide group is attached in the meta position. It is an amide of nicotinic acid. [7] As an aromatic compound, it undergoes electrophilic substitution reactions and transformations of its two functional groups.

  9. Amidine - Wikipedia

    en.wikipedia.org/wiki/Amidine

    The −OH group is replaced by an −NH 2 group and the =O group is replaced by =N R, giving amidines the general structure R n E(=NR)NR 2. [ 10 ] [ 11 ] [ 12 ] When the parent oxoacid is a carboxylic acid , the resulting amidine is a carboxamidine or carboximidamide ( IUPAC name).
