Synthesis of pyrrole 1-3 and 1,4-dihydropyridine derivatives 4-6 were prepared from condensation method and synthesized compounds were screened for environmental biotoxicity such as Brine shrimp cytotoxicity, Ichthyotoxic, Larvicidal and Nematicidial activities. Among the compound 3 and 6 shows that highly toxic (LD50: 8.72 and 12.30 μg/mL) against Brain shrimp cyctotoxic screening and compound 3 and 6 was highly toxicity ( LD50 : 5.01 and 7.75 μg/mL) against Antifeedant screening (ichthyotoxic profile). The compound 3 and 6 was highly active (LD50: 12.88 μg/mL, and 14.79 μg/mL) against Larvicidal activity and compound 3 and 6 was highly active ( LD50 : 8.20 μg/mL, and 7.43 μg/mL) against Nematicidal activity.
Key words: Pyrrole derivative, 1,4-dihydropyridine derivative, Brine shrimp cytotoxicity,
