Structure-activity relationship of pyrrolyl diketo acid derivatives as dual inhibitors of HIV-1 integrase and reverse transcriptase ribonuclease H domain
Open accessAbstract
The development of HIV-1 dual inhibitors is a highly innovative approach aimed at reducing drug toxic side effects as well as therapeutic costs. HIV-1 integrase (IN) and reverse transcriptase-associated ribonuclease H (RNase H) are both selective targets for HIV-1 chemotherapy, and the identification of dual IN/RNase H inhibitors is an attractive strategy for new drug development. We newly synthesized pyrrolyl derivatives that exhibited good potency against IN and a moderate inhibition of the RNase H function of RT, confirming the possibility of developing dual HIV-1 IN/RNase H inhibitors and obtaining new information for the further development of more effective dual HIV-1 inhibitors.

HTPD has a ribonuclease H IC50 below micromolar, antiviral EC50 in the micromolar range, and CC50 above 100 micromolar.
“HTPD exhibited an RNH IC50 below μM, antiviral EC50 in the μM range and CC50 above 100 μM [87].”
From Retroviral RNase H: structure, mechanism, and inhibition (2021) · cites this paper as [87]
The Results and Discussion sections report RNase H inhibition and antiviral activity for pyrrolyl diketo acid derivatives, but do not identify HTPD or give measurements for it. The Cell-Based Assays section reports CC50 >50 μM for the compounds studied, not a CC50 >100 μM for HTPD. Searches for HTPD and the claimed values found no passage that verifies its three measurements. (LLM, conf=0.74)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
