Based on the definitions of pharmacophore and privileged structure, outline essential structural features a 1,4-dihyrdopyridine
stiv31 [10]

Answer:

Explanation:

Pharmacophore (pharmacology) - The molecular framework responsible for a drug's biological activity. According to IUPAC — A pharmacophore is the ensemble of steric and electronic features that is necessary to ensure the optimal supramolecular interactions with a specific biological target structure and to trigger (or to block) its biological response.

Privileged structures are defined as molecular frameworks which are able of providing useful ligands for more than one type of receptor or enzyme target by judicious structural modifications.

1) The 1,4-dihydropyridine ring is present in many biologically important molecules that acts as an important scaffold for cardiovascular drug - a calcium antagonists and although it is technically not considered as a pharmacophore, it is considered as a privileged structure.

1,4-Dihydropyridine (DHP), belongs to the class of calcium antagonist that inhibits the influx of extracellular Ca+2 through the L-type voltage-dependent calcium channels.

A positional substitution in the 4-position is feasible in the heterocyclic ring which in turn culminates in various calcium channel antagonist activities and this heterocyclic ring is the common feature for various pharmacological activities such as anti-inflammatory activity, analgesic activity,

antihypertensive, antianginal, antitumor, antitubercular activity and antithrombotic .

Position on the heterocyclic ring binds to the L-type channel and also to N-type channel on membranes.

2.) The bioisosteres are not a suitable bioisostere for the traditional C-4 aryl or heteroaryl substitution which is necessary for calcium ion blockage thereby inhibiting it to function with the mechanism shared above.

Which qualities describe the entire open-ocean zone?
KengaRu [80]

Answer: The open ocean zone lies beyond the continental slope and contains 65% of the water in the oceans. This zone is divided further into three subzones. The sunlit zone is where photosynthesis takes place. Plankton and jellyfish are drifters that inhabit this zone.

lana66690 [7]
Hello there,

1.) According to the biomolecular data, we COULD infer that <span>humans are more closely related to chimps than any other apes. 

2.) </span>Based on the cladogram, if moths undergo complete metamorphosis, we would MOST LIKELY infer that <span>butterflies and flies do as well. 

3.) </span>According to the cladogram, which of these were the direct ancestors of the Kingdom Fungi? <span>Protista 

4.) </span>Trey is looking at a cell under the microscope. It is attached to many other cells, and it has a nucleus and membrane bound organelles. It has no cell wall. In which kingdom should this organism be classified? <span>Fungi 

5.) </span>A review of the cladogram shows a common ancestor for these four types of vertebrates. Which statement BEST explains the genetics represented by the cladogram? <span>Lizards and snakes are more genetically alike than lizards and birds. 

Hope this helps
