Whаt is the rаtiо оf CATION tо ANION in Drug X? [blаnk1]
Try sоmething а little different - Cоnsider а medicinаl chemistry cоncept called “FRAGMENT BASED LEAD DESIGN” or FBLD. Briefly, FBLD is based on identifying small chemical fragments, which may bind only weakly to the biological target, and then growing/extending or combining them to produce a lead drug compound with a higher affinity. Refer to the figure as needed... Suppose compounds 1 and 2 were designed and tested using FBLD. Compound 1 was found to have 3 µM activity. Compound 2 was found to have 0.5 µM activity. However, when they were joined to form compound 3, the drug had no affinity (>1x103 µM activity) for the receptor in the assay regardless of chain length (n). Assume the experiments were conducted without human error and answer the following questions…. Questions: a) A series of compounds designed by varying chain length in order to find an optimal length (n) is called a [blank1] series. b) Thinking about functional groups…as a result of combining Fragments 1 and 2 to form compound 3, what functional group must be important for activity? briefly explain [blank2] c) Propose a structure combination/orientation between fragments 1 and 2 that could be tested in hopes of obtaining a more active drug candidate? Explain your answer... [blank3] If you need more space to complete your answer, use the scratch paper d) Regardless of how 1 and 2 are combined to form another compound, what activity value would indicate to you the researcher that the new drug you’ve created is MORE ACTIVE than the two original fragments? [blank4] In later testing, it is learned that compound 2, regardless of how it is attached to fragment 1, undergoes aromatic hydroxylation at the position marked with an (#), thus decreasing its IN VIVO activity. e) Aromatic hydroxylation is a [blank5] (phase?) metabolic reaction. remaining blanks on the scratch paper...
