Description

Pirmitegravir is a potent and first-in-class inhibitor of allosteric integrase (ALLINI) that targets LEDGF/p75 binding site. Pirmitegravir displays picomolar IC50 in human PBMCs with a >24,000 therapeutic index against HIV-1. Pirmitegravir harbors outstanding anti-virus and safety properties[1].

IC50 & Target

allosteric integrase (ALLINI)[1]

In Vitro

Pirmitegravir (Compound STP0404) inhibits dual tropic HIV-189.6 at 1.4 nM IC50 in CEMx174 cells[1].
Pirmitegravir (Compound STP0404) is a highly potent ALLINI with picomolar to single-digit nanomolar IC50 values that inhibits both wild type and Ral-resistant HIV-1 strains[1].
Pirmitegravir (Compound STP0404) displays IC50 of 0.41 nM against HIV-1NL4-3 without observable cytotoxicity in human PBMCs at 10 μM (TC50 >10μM)[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Pirmitegravir (Compound STP0404) displays appropriate PK profiles for once daily administration[1].
Pirmitegravir (Compound STP0404) lacks micronucleus-inducing and bone marrow cell proliferation inhibitory potentials in rats (500, 1000 and 2000 mg/kg/day), supporting that STP0404 is not genotoxic[1].
Assessment of Pharmacokinetics (PK) profile of Pirmitegravir (Compound STP0404) in rat and dog[1].

PK Values Rat Dog
10 mg/kg (p.o) 5 mg/kg (i.v) 2 mg/kg (p.o) 2 mg/kg (i.v)
T1/2 (hr) 4.56 3.83 6.90 6.11
AUC (hr.nM) 78074 42676 4683 9260
Cmax (nM) 21380 - 3983 -
Ft (%) 92.8 - 50.6 -

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: SD rats and beagle dogs[1]
Dosage: 1, 2, 5, and 10 mg/kg
Administration: i.v.; p.o.
Result: The half-life (T1/2) was 3–7 h, and oral bioavailability (Ft) was 50–93% in these two animal species. Systemic exposure, which was determined by area under the curve and maximum concentration of STP0404 in plasma (AUC and Cmax), increased dose-dependently from 2 to 10 mg/kg.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
