The design, synthesis and anti HIV-1 replication inhibition of 3-(cyclopropylethynyl)-3-hydroxy-indolin-2- ones, analogues of efavirenz (Sustiva™), are described. Different substituted isatins were used to generate final products that contain pharmacophoric features for RT inhibition, such as the oxoindole and cyclopropylethynyl groups. The suitability of the indolin-2-one ring in the planned compounds in replacement to the benzoxazinone ring of efavirenz was proven, since compound 15 presented a greater activity than efavirenz against HIV-1 replication and was not significantly cytotoxic.
