analogs & derivatives definition: Used with drugs and chemicals for substances that share the same parent molecule or have similar electronic structure but differ by the addition or substitution of other atoms or molecules. It is used when the specific chemical heading is not available and no appropriate group heading exists.
Atropine Derivatives definition: Analogs and derivatives of atropine.
Bephenium Compounds definition: Analogs or derivatives of bephenium (N,N-dimethyl-N-(2-phenoxyethyl)benzenemethanaminium).
Morphine Derivatives definition: Analogs or derivatives of morphine.
Retinoids definition: A group of tetraterpenes, with four terpene units joined head-to-tail. Biologically active members of this class are used clinically in the treatment of severe cystic ACNE; PSORIASIS; and other disorders of keratinization.
retinoid definition: retinol and its derivatives; C(20) polyunsaturated, cyclic, lipid soluble alcohol; deficiency results in night blindness and certain epithelial disorders.
retinoid definition: Vitamin A or a vitamin A-like compound.
Retinoic Acid Agent definition: A group of agents that includes retinol (Vitamin A) and related compounds with potential antineoplastic and/or chemopreventive activities. A retinoic acid agent binds to and/or activates specific nuclear retinoic acid receptors (RARs) and retinoid X receptors (RXRs), thereby modulating transcription of genes responsible for cell differentiation and proliferation. A retinoic acid agent may exhibit immunomodulatory and anti-inflammatory properties and may inhibit ornithine decarboxylase, resulting in a decrease in polyamine synthesis and keratinization. (NCI04)
Scopolamine Derivatives definition: Analogs or derivatives of scopolamine.
TEST REAGENTS FOR SULPHANIMIDE DERIVATIVES definition: A sulfonamide test system is a device intended to measure sulfonamides, any of the antibacterial drugs derived from sulfanilamide, in human specimens. Measurements obtained by this device are used in the diagnosis and treatment of sulfonamide overdose and in monitoring sulfonamide levels to ensure appropriate therapy.
