Steroid amino acid

Colourless Substances e.g., alkaloids, steroids, amino acids and the like may be detected under short-wave UV-light or a long-wave UV-light. These substances may also be detected as brown/dark brown spots when exposed to I2-vapours in a closed dessicator.

This present chapter is devoted to the recent advances, for the last decade, in fluorinated analogues of natural products developed as pharmaceuticals and now/ marketed or in development (registered or in clinical development). These mainly concern fluorine-substituted nucleosides, alkaloids, macrolides, steroids, amino acids and prostaglandins.

A novel steroidal cyclopeptide (Figure 38) has been synthesized by Albert and Feigel from a steroidal amino acid [55]. Since a variety of amino acids can be incorporated into the macrocycle, this strategy offers attractive possibilities for the construction of functionalized macrocycles for catalyst design.

In 2013, AuCls was found to enable the stereoselective glycosidation of propargyl 1,2-orthoester of arabinofuranose 48 with various aglycones (aliphatic, aromatic, steroidal, amino acid) and sugar-based aglycones to afford corresponding 1,2-trans arabinofuranosides by Hotha and... 

Natural and/or synthesized aziridine-containing compounds, lipids, steroids, amino acids, as well as their peptide derivatives have shown to be promising candidates for the development of new dmgs toward several diseases, especially neoplasms. No doubt incorporation of an aziridine warhead will allow development of interesting new synthetic and semisynthetic compounds with clinical utility. 

Selective adsorption properties are obtained from the structure, controlled distribution of pore sizes, high surface areas and chemical nature of the matrix. Applications include the recovery of a wide range of solutes from the aqueous phase, including phenol, benzene, toluene, chlorinated organics, PCBs, pesticides, antibiotics, acetone, ethanol, detergents, emulsifiers, dyes, steroids, amino acids, etc. Regeneration may be effected by a variety of methods which include steam desorption, solvent elution, pH change and chemical extraction.
