Ribociclib Succinate (CAS 1374639-75-4), chemically designated as ribociclib hydrogen succinate with the molecular formula (C₂₃H₃₀N₈O)(C₄H₅O₄), is a selective inhibitor of cyclin-dependent kinases CDK4 and CDK6 in succinate salt form .

Kopyrrol (CAS 55921-65-8), chemically known as pyrrolidinyl diaminopyrimidine oxide, is a water-soluble hair growth promoter structurally related to minoxidil. The molecule features a pyrimidine core bearing two amino groups and an N-oxide functionality at the 3-position, with a pyrrolidine ring attached at the 6-position.

Polyoxyl 15 Hydroxystearate (CAS 70142-34-6), also known as Macrogol 15 hydroxystearate or Solutol HS 15, is a non-ionic surfactant and emulsifier produced by reacting approximately 15 moles of ethylene oxide with 1 mole of 12-hydroxystearic acid.

Kopexil (CAS 74638-76-9), also known as 2,4-diaminopyrimidine-3-oxide or Aminexil, is a low-molecular-weight heterocyclic compound structurally related to minoxidil. The molecule consists of a pyrimidine ring bearing two amino groups at the 2- and 4-positions and an N-oxide functionality at the 3-position.

Creatine Phosphate Disodium Salt (Phosphocreatine disodium salt, CAS 922-32-7) is the disodium salt form of creatine phosphate, a naturally occurring phosphorylated guanidino compound that serves as a high-energy phosphate reservoir in vertebrate skeletal muscle, cardiac muscle, and brain. Structurally, Creatine Phosphate Disodium Salt consists of a creatine backbone (N-methylglycine) with a phosphoramidate group attached to the guanidino nitrogen, existing as the disodium salt.

Isoprenaline Hydrochloride (Isoproterenol hydrochloride, CAS 51-30-9) is the hydrochloride salt form of isoprenaline, a synthetic catecholamine and non-selective β-adrenoceptor agonist. The molecule features a catechol (3,4-dihydroxyphenyl) core with a hydroxyethyl side chain bearing an isopropylamino substituent, forming the characteristic β-ethanolamine pharmacophore of adrenergic agonists. As a hydrochloride salt,
