A series of 1,4-disubstituted piperazine derivatives comprised of indol-3-ylalkyl and substituted pyridin-2-yl substituent groups. These compounds are useful as antidepressant agents.
Certain 1-indolylalkyl-4-(alkoxypyrimidinyl)piperazines of Formula I are useful antidepressant agents. The ##STR1## substituents R.sup.1, R.sup.2 and R.sup.5 are hydrogen or lower alkyl; R.sup.3 and R.sup.4 are hydrogen, alkyl, alkoxy, alkythio, carboxamido, halo, or trifluoromethyl; R.sup.6 is alkoxy; and n is the integer 2 or 3.
4-ιndol-3-yl)thiazole acylamines. An evaluation of antibacterial activity againstGram (+) and Gram (−) bacteria revealed that the MIC of indole derivatives is in the range of 0.06–1.88 mg/mL, while among fourteen methylindole derivatives, only six were active, with an MIC in the range of of 0.47–1.88 mg/mL. S. aureus appeared to be the most resistant strain, while S. Typhimurium was the most sensitive
