Over 80-years, 24 sulfate salts were approved and presented in Figs. 4–6. These salts are categorized based on the chemical class of API, such as amino-heterocycles, alkylamines, guanidines, amino sugars, and peptides. Hydroxychloroquine (HCQ) is an amino-heterocycle class of API ...

Boronic acids act as Lewis acids because of the empty p-orbital on boron, and in the presence of Lewis bases such as hydroxyl groups, interconversion from sp2 to sp3 hybridization readily occurs.20–22 In aqueous media, a water molecule reversibly adds to a neutral trigonal form (I) of ...
miscible with water, alcohol, ether, benzene, chloroform, and acetone, but incompatible with strong oxidisers, strong bases, strong alkalies and pure nitrogen. It may polymerize (sometimes explosively) when contacting with amines, ammonia, oleum and chlorosulfonic acid, iron salts and peroxides[2]...

The DNA sequence of the syn-taqIIRM gene is shown in black bold letters and the changed bases are marked in red. The crucial amino acids of the catalytic centres are dark red, bold and underlined. The functional protein domains are marked as follows: REase domain in blue, helical domain ...
Prepare a TLC cellulose plate of 10 cm×10 cm with the origin at the lower left corner, 1 cm distant from both edges. • Apply ca. 1–2 µl of cell-wall hydrolysate using a glass capillary to the origin and allow it to dry. • Develop the chromatogram in a TLC tank lined wi...
