Concept-

  • Drugs are chemicals of low molecular masses.
  • These interact with macromolecular targets and produce a biological response.
  • When the biological response is therapeutic and useful, these chemicals are called medicines and are used in the diagnosis, prevention, and treatment of diseases.
  • If taken in doses higher than those recommended, most of the drugs used as medicines are potential poisons.
  • The use of chemicals for therapeutic effect is called chemotherapy.

Explanation-

  • Antifertility drugs are birth control pills that essentially contain a mixture of synthetic estrogen and progesterone derivatives.
  • Both of these compounds are hormones.
  • It is known that progesterone suppresses ovulation.
  • Synthetic progesterone derivatives are more potent than progesterone.
  • Norethindrone is an example of a synthetic progesterone derivative most widely used as an antifertility drug.
  • The estrogen derivative which is used in combination with progesterone derivative is ethynylestradiol (novestrol).

Therefore the antifertility drug is novestrol.

Prontosil

  • In 1932, he succeeded in preparing the first effective antibacterial agent, prontosil, which resembles in structure to the compound, salvarsan.

  • Thus the sulpha drugs were discovered.
