-
beta-blocker
-
beta blocker and calcium channel blocker
-
pH indicator
-
calcium indicator
-
both (1) and (2)
D
Correct answer
Explanation
This option is correct because indol-1 is a popular calcium indicator similar to fura-2. In contrast to fura-2, indol-1 has a dual emission peak in Ca free solution in 475 nm while in the presence of Ca, the emission is shifted to 400 nm.

ADME cal
-
None of these
A
Correct answer
Explanation
ADME-TOX prediction tools help forecast Absorption, Distribution, Metabolism, Excretion, and Toxicity properties of drug candidates. 'ADME predictor' is the standard naming convention for such tools.

QSAR
-
pharmacophore mapping
-
docking
A
Correct answer
Explanation
De novo drug design involves building drug molecules atom-by-atom or from fragments to fit a specific receptor binding site, unlike docking which studies existing molecules or QSAR which uses statistical correlations.
