been found useful against tumors, viral diseases and can also act as immunesuppressants. This peptide is primarily derived from the Caribbean tunicate of
Trididemnum (Rinehart et al. 1990).
It is noteworthy that, Didemnin B is a well-known member of the family because
of its powerful antitumor action (Rinehart et al. 1990). It is noted that, Didemnin B
possesses excellent ability as producers of antiproliferative compounds along with
antitumor properties. It is used widely for cure of prostatic cancer (Geldof et al.
1999). Didemnim A and B, otherwise known as bioactive substances, may be effective for dissimilar varieties of virus such as parainfluenza, herpes simplex, and dengue virus (Canonico et al. 1982). A BAP Styelin D bearing 32-units with amide
group at C-terminal, derived from hemocytes of Styela clava, an ascidian, was
shown to have antibacterial action against gram positive and negative bacteria residing in salty condition (De Vries and Beart 1995; Taylor et al. 2000).
5.2.8 Bioactive Peptides from Fungi Sources
Penicillium algidum, a fungus, on hydrolysis liberates two known cyclic peptide i.e.
cycloaspeptide A and cycloaspeptide D and cyclic nitro peptide psychrophilin
D. Biological analyses indicate that they are biologically active against cancer,
malaria, certain viruses and other microbes. Nitropeptide, psychrophilin D showed
moderate action against blood and bone marrow cancer P388 in rodents, while peptides cycloaspeptide A and D showed moderate action against malaria caused by
Plasmodium falciparum (Dalsgaard et al. 2005).
Fungi release multiple peptides and cyclopeptides such as cephalosporins and
penicillins (Kozák et al. 2018). Emodepsin, a semisynthetic Emodepsin, also known
as depsipeptide, may have use against parasitic worms among animals (Woods et al.
2018). Structural diversity of different peptides shows different biological action
(Wang et al. 2018). A fungus-derived peptide known as Gliotoxin, reside in subject
of aspergillosis affecting their cell by retarding their binding capacity. Moreover, it
reduces the immune capability and persuades the apoptosis action in affected cells
(Bertuzzi et al. 2018).
It is observed that BAPs from Apicidin F, JM47, chlamydocins and FR235222
have biological action against protozoans and can retard the growth of cells and
inhibit immune capacity, eventually causing cell death. In addition to the abovementioned properties, these peptides also show antiplasmodial potential (Yang
et al. 2018).
A depsipeptide called Aspergillicin obtain from fungi used to regulate immune
system. Cyclodepsipeptides, Stevastelins have a lipotropic terminal. It has the ability to inhibit the activity of human T-cells but has less toxic effect in mice (Wang
et al. 2018).
A cyclic depsipeptide called Verticilide was isolated from Verticillium species
can make ryanodine less effective in binding with receptor and acts as a biological
agent against insects. Cycloaspeptide A and D derived from fungi are considered to
be most potent biological agents against parasites (Anke and Laatsch 2018).
