activity. In fact, this possibility had been predicted by in-silico PASS prediction,
and our in vitro findings show that piperine reduces the peak current of the Na C
isoform Nav1.4 canal.
We note also that Nav1.4 converts the muscle tissue isoform of sodium channels,
but many of the antagonistic locations are preserved in the sodium channel family
as well as we thus anticipate that other types of sodium channels, including neuronal ones, would also be similarly blocked (Fozzard et al. 2005). Therefore, it is
possible that piperine in animal models evaluated by inhibiting sodium channel
interaction may reflect its anti-convulsive attributes. We further found that the
TRPV1 receptor has also, in recent times, reported to play a role in the epileptogenesis method. TRPV1 is a broad—spectrum, high Ca
2+ permeability cation
channel (Kauer and Gibson 2009), and this specific receptors usually promotes the
release of glutamate by boosting the excitability of neurons and synaptic
C-terminals (Chávez et al. 2010; Gibson et al. 2008; Schöbel et al. 2012; Zsombok
et al. 2011). Piperine has been shown to inhibit TRPV1 receptors, and this activity
may thus also contribute to the anticonvulsant action of this compound (Chen et al.
2013; McNamara et al. 2005), perhaps in conjunction with sodium channel block.
22.12 Immunomodulatory and Antitumor Activity
The dosage of piperine was selected on the basis of cytotoxicity. 1.14 mg/dose/
animal for piperine is the lowest concentration with maximum activity.
Administration of piperine showed increased number of total WBC count. This
indicates piperine can stimulate the hemopoietic system. The differential count
shows the drug did not alter the ratio of different WBC types. Bone marrow fills in
as the significant wellspring of all blood cells, including lymphocytes.
Administration of piperine demonstrated an expansion in bone marrow cellularity
and a-esterase positive cells showing its impact on stem cell multiplication.
Piperine was found to expand the coursing immunizer titer and counter-acting agent
framing cells demonstrating its stimulatory impact on the humoral arm of the
immune system. Administration of piperine could likewise altogether repress the
development of strong tumor incited by DLA cells and ascites tumor instigated by
EAC cells. Immunomodulators may enact cytotoxic effector cells, for example,
cytotoxic T lymphocytes, natural killer (NK) lymphocytes, macrophages, and initiated neutrophils (Fidler 1985, 1988). Utilization of chemotherapy in addition to
target-explicit immunomodulators hold a sensible guarantee for clinical utility in
future (Sunila and Kuttan 2004). Immunomodulatory activity of piperine may be
due to the combined action of humoral and cell-mediated immune responses.
Hence, the results indicated that piperine could act as a non-toxic immunomodulator which possesses antitumor property also (Sunila and Kuttan 2004).
