Small-molecule inhibition of human immunodeficiency virus type 1 replication by specific targeting of the final step of virion maturation.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Despite the effectiveness of currently available human immunodeficiency virus type 1 (HIV-1) therapies, a continuing need exists for new drugs to treat HIV-1 infection. We investigated the mechanism by which 3-O-[3',3'-dimethylsuccinyl]-betulinic acid (DSB) inhibits HIV-1 replication. DSB functions at a late stage of the virus life cycle but does not inhibit the HIV-1 protease in vitro or interfere with virus assembly or release. DSB specifically delays the cleavage of Gag between the capsid (CA) and p2, resulting in delayed formation of the mature viral core and reduced HIV-1 infectivity. Replication of simian immunodeficiency virus (SIV) was resistant to DSB; however, a chimeric SIV carrying CA-p2 sequences from HIV-1 was inhibited by the drug, indicating that susceptibility to DSB maps to the CA-p2 region of the HIV-1 Gag protein. A single point mutation at the CA-p2 cleavage site of HIV-1 conferred strong resistance to DSB, confirming the target of the drug. HIV-1 strains that are resistant to a variety of protease inhibitors were sensitive to DSB. These findings indicate that DSB specifically protects the CA-p2 cleavage site from processing by the viral protease during virion maturation, thereby revealing a novel mechanism for pharmacologic inhibition of HIV-1 replication.
