Modified Borntrager Test

modified borntrager's test is chemical test used to detect the presence of anthraquinone moiety in some glycosides.

Process:

  1. Drug + Dil. H2SO4 
  2. + Ferric Chloride 
  3. Boil in Water Bath and then cool 
  4. Filter 
  5. Extract with CCl4/Benzene 
  6. Ammonium Sol Added 
Observation: Pink or Red Colour confirms the presence of Anthraquinone Moiety

 Cardiac Glycoside  DEF - Cardiac glycosides are a class of organic compounds that increase the output force of the heart and decrease its rate of contractions by inhibiting the cellular sodium-potassium ATPase pump. General structure- The general structure of a cardiac glycoside consists of a  steroid  molecule attached to a sugar ( glycoside ) and an R group. [4]  The steroid nucleus consists of four fused rings to which other functional groups such as  methyl ,  hydroxyl , and  aldehyde  groups can be attached to influence the overall molecule's biological activity. [4]  Cardiac glycosides also vary in the groups attached at either end of the steroid. ð   All glycosides consists of an aglycone which is attached to one or more sugar (glycone) moieties. ð   The Aglycone part have the pharmacological activity → Attached sugar moiety modify the solubility and Permeability. ð   The Aglycone part consist of Cyclopentanope...

Utilization of Vinca alkaloids Chemotherapy for Cancer : Vinca alkaloids are used in chemotherapy for cancer.  Anti tumor  Immunosuppressive Drugs : Vinca alkaloids are now produced synthetically and used as drugs in cancer therapy and as immunosuppressive drugs. Antihypertensive Properties : Vinpocetine, a semi-synthetic derivative of vincamine, has demonstrated antihypertensive effects by improving blood circulation and reducing peripheral resistance. Neuroprotective Properties : Vinca alkaloids have shown neuroprotective potential against various neurological disorders, including Alzheimer's disease and Parkinson's disease. vincristine (a) and vinblastine (b)
