Primulin
Based on 1 Customer Validation
Primulin is a versatile fluorescent dye and bioactive compound widely used in analytical, biological, botanical and virological studies. Primulin acts as a versatile stain that labels plant cell walls and differentiates live and dead spermatozoa via distinct fluorescence patterns. Primulin exhibits strong albumin‑binding capacity. Primulin acts as a retrograde axonal tracer in neurobiological investigations. Primulin and its derivatives inhibit HCV NS3, block dengue virus NS3-mediated ATP hydrolysis, and disrupt HCV replicase assembly.

Descripciòn
In Vitro
Primulin is a versatile fluorescent stain that labels plant cell walls[1][2][3].
Primulin (10 μM, 72 h) neither reduces HCV replication complex numbers nor inhibits cellular NS3 protease activity in Huh7.5/HCV Con1sg Rluc replicon cells[1].
Primulin is an acid thiazole dye with stable fluorescence that binds to bovine albumin, is excluded by intact dorsal root ganglion neurons, and diffuses into neurons after freezing and thawing[2].
Primulin binds non‑covalently to lipids and enables phospholipid visualization on TLC plates without interfering with mass spectrometry analysis[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. .

Cell Line:Huh7.5/HCV Con1sg Rluc replicon stable cells
-
Concentration:10 μM
-
Incubation Time:72 h
-
Result:Did not influence the number of HCV replication complexes.
In Vivo
Primulin (5%; intramuscular into vibrissae muscles; single dose; bilateral) accumulation in regenerating facial neurons is significantly increased by ~200% of control levels at 11 days post-crush during mouse facial nerve regeneration[2].
Primulin (5-10%; bilateral intramuscular injection into vibrissae muscles)reduces accumulation in facial neurons after botulinum toxin paralysis. Low-dose tetanus toxin increases primulin accumulation, while high-dose decreases it by 17%[2].

Animal Model:Swiss albino mice (2-month-old, unspecified gender)[2]
-
Dosage:2%, 5%, 10%, 20% (50 μl)
-
Administration:intramuscular into vibrissae muscles; single dose
-
Result:Labeled approximately 30% of facial neurons with 2% primuline.
Labeled nearly all facial neurons with 5% primuline.
Enhanced fluorescence intensity in facial neurons in a concentration‑dependent manner.
Elevated fluorescence intensity in facial neurons in a time‑dependent manner after 5% primuline injection.
Produced no ultrastructural alterations in motor endplates at 5-20% concentrations.
-
Animal Model:Swiss albino mice (2-month-old, unspecified gender, facial nerve crushed at exit from stylomastoid foramen)[2]
-
Dosage:5% (50 μl)
-
Administration:intramuscular into vibrissae muscles; single dose; bilateral
-
Result:Blocked primulin transport to facial neurons immediately and 3 days after nerve crush.
Increased primulin accumulation on the crushed side to ~200% of controls at 11 days.
Elevated primulin accumulation to ~135% and ~125% of controls at 18 and 34 days.
Showed no significant difference in primulin accumulation between groups at 92 days.
-

-
Administration:intramuscular into vibrissae muscles; single dose; bilateral
-
Result:Reduced primulin fluorescence intensity by 7-19% on the toxin‑treated side in mice with ipsilateral vibrissae paralysis.
Showed no significant difference in primulin fluorescence intensity between both sides in mice with bilateral paralysis.
-
Animal Model:Swiss albino mice (2-month-old, unspecified gender, tetanus toxin injected into left vibrissae muscles)[2]
-
Dosage:5%, 10% (5 μl)
-
Administration:intramuscular into vibrissae muscles; single dose; bilateral
-
Result:Increased primulin fluorescence intensity by 11-23% on the treated side in mice with low‑dose tetanus toxin.
Reduced primulin fluorescence intensity by 17% on the treated side in mice with high‑dose tetanus toxin‑induced paralysis.
