Malpinin A

Name: Malpinin A
Brand: MedChemExpress
SKU: HY-P11862
Availability: PreOrder

(Synonyms: MBJ-0173)

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.

For research use only. We do not sell to patients.

Biological Activity

Description

In Vitro

Anti-cancerBacterial Infection

Anti-cancer

Malpinin A (100 μM) shows no significant cytotoxicity against SKOV-3, ACC-MESO-1, or Jurkat cells at a concentration of 100 μM^[2].

Bacterial Infection

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.

In Vivo

Parasitic Infection

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].
Malpinin A (5.45 μg mL^-1-4× IC₅₀ concentration; exposure in culture media) potently inhibits C. elegans proliferation and feeding with an IC₅₀ of 6.35 μM, leading to reduced survival and larval hatching at higher doses^[1].

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

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.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
