Black mold works antiviral

Have you ever wondered why never catch a cold anymore since you have ME or CFS?

Maybe you suffer from mold intoxication. Some people simply cannot eliminate the neurotoxines released by mold. Some bacteria like Lyme, bartonella and babesia produce the same symptoms. Blue green algue, ciguaterae, chlamydia pneumonia, ... yessss same effect.

Sick building syndrome is not a new concept but a severely underestimated factor in ME. Why do doctors don't ever ask you if you have a leaky roof at your work or house, have musty tiles in the bathroom, HVAC at work, did you work as an airhostess,  ... Maybe it is like opening a jar of worms because fixing mold is very expensive.
If it is at your work, change! If it is your house, move! If none of it is possible, think about it again!

Never ever try to remove the mold yourself. Never! You can die from it. Period. Google a professional. Check with your insurance company what can be done.

Stachyflin and acetylstachyflin, novel anti-influenza A virus substances, produced by Stachybotrys (black mold) sp. RF-7260. I. Isolation, structure elucidation and biological activities. J Antibiot (Tokyo). 2002 Feb;55(2):155-64. PMID: 12002997

Two novel compounds, stachyflin and acetylstachyflin, have been isolated by solid-state fermentation of Stachybotrys sp. RF-7260.

Stachyflin showed antiviral activity against influenza A virus (H1N1) in vitro with an IC50 value of 0.003 microM. Acetylstachyflin was about 77-fold less active than stachyflin.

A new strategy directed toward the total synthesis of stachyflin, a potent and novel anti-influenza A virus agent isolated from a microorganism, has been presented through the enantioselective synthesis of the tetracyclic core structure. The synthetic method features a BF3Et2O-induced domino epoxide-opening/rearrangement/cyclization reaction as the key step.

Stachybotrys sp. RF-7260 was found to produce stachyflins, novel anti-influenza virus agents, under solid-state fermentation conditions. Feeding DL-lysine to a culture of Stachybotrys sp. RF-7260 induced the formation of the novel compounds, SQ-02-S-L2 and -L1, and feeding DL-valine the formation of SQ-02-S-VI and -V2. The structures of these metabolites were determined by detailed 2D NMR analyses in comparison with acetylstachyflin. SQ-02-S-L2 and -L1 have the lysine moiety and SQ-02-S-V1 has the valine moiety. SQ-02-S-V2 has an amidine moiety instead of the lactam moiety in acetylstachyflin. SQ-02-S-L2, -L1 and -V1, substituted on the lactam amide hydrogen, displayed only a low level of the antiviral activity. However, deacetyl SQ-02-S-V2 showed potent antiviral activity similar to stachyflin.

The effect of trichothecene mycotoxins, deoxynivalenol (DON), fusarenon-X (FX) and nivalenol (NIV), on plaque formation of herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) in HEp-2 cells was examined.

The 50% effective concentrations (EC50) of DON, FX, and NIV for HSV-1 plaque formation were 160, 56, and 120 ng/ml, respectively. Those for HSV-2 plaque formation were 94, 26, and 50 ng/ml, respectively. These three mycotoxins showed about 2-fold higher selectivity to HSV-2 than to HSV-1. Plaque formation of HSV-1 was not inhibited with trichothecenes at concentrations completely inhibiting plaque formation when cells were treated during virus adsorption period or 15 hr before infection.

These results indicate that trichothecenes affect replication of HSV-1 after virus adsorption, but not before or during virus adsorption to the host cells.

Two known spirodihydrobenzofuran terpenes (1 and 2) were isolated from a mycelium extract of the fungus Stachybotrys nephrospora BCC 3900. Compound 1 (Mer-NF5003F or stachybotrydial) exhibited potent antiviral activity (the IC50 value of 4.32 microg/mL) comparable to the standard drug, acyclovir, while compound 2 was inactive against the HSV-1 virus. Both 1 and 2 possessed antiplasmodial activity (IC50 values of 0.85 and 0.15 microg/mL for 1 and 2, respectively), and were not toxic towards the Vero cell line. A regiospecific conversion of the dialdehyde 1 to the lactone 2 proceeded simply under acidic conditions.
