LEDGINs, non-catalytic site inhibitors of HIV-1 integrase: a patent review (2006 – 2014)
Bibliographic record
Abstract
INTRODUCTION: Integration of the viral genome into the host cell chromatin is a central step in the replication cycle of the HIV. Blocking the viral integrase (IN) enzyme therefore provides an attractive therapeutic strategy, as evidenced by the recent clinical approval of three IN strand transfer inhibitors. Viral resistance and cross-resistance among these inhibitors, however, warrant the search for compounds targeting HIV integration through alternative mechanisms of action. AREAS COVERED: The most potent class of allosteric IN inhibitors was independently identified at the University of Leuven, Belgium, and at Boehringer Ingelheim, Canada. These compounds, coined LEDGINs (after the lens epithelium-derived growth factor/p75 cofactor binding pocket on IN) or non-catalytic site IN inhibitors (NCINIs) by the respective groups, have shown remarkable antiviral activity. This review provides a brief introduction to the compound class and discusses the recent patent literature (2006 to the present). EXPERT OPINION: LEDGINs are still early in development. Trials with clinical candidate BI-224436 were put on hold despite promising results. Literature, however, reveals that almost all major pharmaceutical companies active in the treatment of HIV/AIDS have taken a significant interest in this class. As a result, several of these inhibitors may soon enter clinical trials.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
