Malpinin A
Malpinin A (MBJ-0173) is a dehydrohexapeptide biosurfactant with significant anthelmintic activity. Malpinin A specifically accumulates in the nematode digestive tract, thereby effectively inhibiting nematode feeding and proliferation without causing paralysis. Malpinin A can be used in studies related to plant-parasitic nematode infection.

Biological Activity
Malpinin A (100 μM) shows no significant cytotoxicity against SKOV-3, ACC-MESO-1, or Jurkat cells at a concentration of 100 μM[2].
Malpinin A (10 μg) shows no antibacterial activity against Micrococcus luteus at a dose of 10 μg per disk[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Malpinin A (100 μg mL-1; supplementation of fungal culture media) at 100 μg mL-1 confers nematode protection to M. indohii, significantly reducing Aphelenchus avenae propagation[1].

Animal Model:unspecified strain (adult hermaphrodites, stage L3−4 larvae)[1]
-
Dosage:5.45 μg mL-1 (IC50 concentration); 11.6 μM (2× IC50 concentration); 4× IC50 concentration
-
Administration:exposure in culture media
-
Result:Exhibited anthelminthic activity with an IC50 of 5.45 μg mL-1.
Killed or nearly immobilized nematodes at 4× IC50, with only very few larvae hatching compared to untreated controls.
Ceased nematode feeding on bacterial food sources without immediately affecting motility.
-
Animal Model:unspecified strain[1]
-
Dosage:100 μg mL-1
-
Administration:supplementation of fungal culture media
-
Result:Reduced *Aphelenchus avenae* propagation drastically, with nematode numbers comparable to levels seen in cocultures with *M. alpina* (natural malpinin producer).
-
Animal Model:unspecified strain (adult hermaphrodites, larvae)[1]
-
Dosage:16.92 μM (malpinin A-FAM, IC50); 110 μM (malpinin A-alkyne, Raman imaging); 31 μM (malpinin A-alkyne, full anthelminthic inhibition)
-
Administration:exposure in culture media
-
Result:Showed high fluorescence emission originating from the entire digestive tract, including the pharynx and grinder region, in both larvae and adults via malpinin A-FAM imaging.
Distinguished malpinin A-FAM signal from autofluorescence via FLIM, confirming accumulation in the intestinal lumen.
Confirmed accumulation in the pharyngeal lumen, parts of the grinder, and the intestine via alkyne-tagged malpinin A Raman microspectroscopy.
