Juvabione is the methyl ester of todomatuic acid, both of which are sesquiterpenes (C15) found in the wood of true firs of the genus Abies. They exist as part of a mixture of sesquiterpenes based on the bisabolane scaffold. Sesquiterpenes of this family,
C19 Ceramide is a naturally occurring ceramide that has been found in J. juncea extracts as well as rat brain and mouse heart.[1],[2],[3] It is elevated in adult and decreased in juvenile whole rat brain extracts by 114 and 37%, respectively, following chronic ethanol exposure.[2] C19 Ceramide is also increased in mouse hearts following administration of angiotensin II.[3]
TFM is a piscicide.1It is toxic to sea lamprey (P. marinus) with LC50values ranging from 1.97 to 2.11 and 2.05 to 2.21 mg/L for sac and swim-up fry, respectively, 1.6 to 2.45 mg/L for juveniles, and 1.6 to 1.63 mg/L for adults. It is also toxic to juvenile lake sturgeon (A. fulvescens) less than 100 mm in size but not to a variety of other fish species. TFM (50 μM) uncouples oxidative phosphorylation by 22 and 28% in isolated sea lamprey and rainbow trout (O. mykiss) liver, respectively.2Formulations containing TFM have been used as lampricides in the control of larval sea lamprey populations. 1.Boogaard, M.A., Bills, T.D., and Johnson, D.A.Acute toxicity of TFM and a TFM/niclosamide mixture to selected species of fish, including lake sturgeon (Acipenser fulvescens) and mudpuppies (Necturus maculosus), in laboratory and field exposuresJ.

Gepotidacin hydrochloride, also known as GSK-2140944 hydrochloride, is a potent Type II DNA topoisomerase inhibitor. Gepotidacin hydrochloride is a novel antibacterial drug candidate. Gepotidacin hydrochloride Demonstrates Absence of Fluoroquinolone-Like Arthropathy in Juvenile Rats. Gepotidacin hydrochloride is efficacious in a nonhuman primate model of pneumonic plague. When tested against Gram-negative (n = 333) and Gram-positive (n = 225) anaerobes by agar dilution, Gepotidacin hydrochloride inhibited 90% of isolates at concentrations of 4 and 2 μg mL, respectively.
Thymic factor X (TFX-Jelfa) is an aqueous extract derived from the thymus of a juvenile calf and serves as a natural stimulator of lymphocyte function.
Allatostatin IV, an octapeptide amine, is a member of the allatoregulatory peptide family found in insects which either inhibit (allatostatins) or stimulate (allatotropins) juvenile hormone (JH) synthesis.
