View Full Version : phenomenally pheromonal molecular hybrid hypothesis
Archetypical Hybrid (HEC)

PREFACE: Hello, I'm the archetypical hybrid
(HEC):wave:
I'm a student majoring in neuropharmacology, organic chemistry, chemical &
mechanical engineering, and I'm conducting some private research on phenomenal pheromones as described
hereafter.
For your referances:
androsta-4,16-dien-3-one =
androstadienone
5α-androstan-3-one =
androstAnone
5α-androst-16-en-3-one = androstenone
4-androsten-3-one
= 4-androstenone
Based upon the quantitative structure-property relationships I've studied for
steroids which are active at the human female VNO, I believe that 4-ANDROSTEN-3-ONE (DESOXYTESTOSTERONE), may be
very active at the human female VNO. This hypothesis is derived from the fact that only two pheromones:
androsta-4,16-dien-3-one, and 5α-androstan-3-one are significantly active at the human female
VNO [as substantiated by an Erox study long ago titled: the sixth sense].
5α-androstan-3-one is a saturated analogue of 5α-androst-16-en-3-one (a pig
pheromone), which has an alkene group at the 16th carbon of the prototypical skeletal molecule.
5α-androst-16-en-3-one does not target the human female VNO, whereas
5α-androstan-3-one does; the only difference being the alkene group at the 16th carbon. Now,
androsta-4,16-dien-3-one, an analogue of 5α-androst-16-en-3-one is very active at the human
female VNO, the only difference between the two being an alkene group at the 4th carbon.

From logical deduction and
quantitative structure-property relationships, I assert the following:
A) An alkene group at the 3rd carbon of
the skeletal molecule dramatically increases activity at the VNO
B) A fully saturated group at the 16th-17th
carbons also significantly increases activity.
EPILOGUE: Therefore, it is my hypothesis that
4-androsten-3-one, as a molecular hybrid containing the most desired substitutions may be very active at the human
female VNO, more so than the archetypical androsta-4,16-dien-3-one. If possible I ask for you good folks within this
esoteric paradigm to voice your opinion with respect to this hypothesis.:think:

Please comment on any
recent research that you may be familiar with that in any way indicates the human VNO is important to pheromonal
effects? I don't know of any olfactory researchers who are much interested, if at all, in pursuing its hypothetical
function. Besides, we've already learned that the main olfactory system is involved in pheromone detection in
several mammalian species that don't require a VNO to respond to pheromones with changes in
behavior.

Hi Mr.
Archetypical Hybrid (HEC):wave:
Good to see an interesting post like that :goodpost:
Androsta-4,16-dien-3-one (A1) and estra-1,3,5(10),16-tetraen-3-ol (Estratetraenol) were
both shown to activate the VNO according to Erox's studies (they do have the patent on the two compounds though):
http://www.erox.com/SixthSense/StoryOne.html[
/FONT] (http://www.erox.com/SixthSense/StoryOne.html)
[FONT=Arial]You wrote that 5α-androstan-3-one activates the human VNO but I have not seen any
literature supporting this assertion on the internet. In any case we can test what this compound does in real-life
as we now have AndrostAnone (the same pheromone as 5α-androstan-3-one?) available to buy as a chemistry set

As for your
hypothesis that "4-androsten-3-one, as a molecular hybrid containing the most desired substitutions may be very
active at the human female VNO, more so than the archetypical androsta-4,16-dien-3-one", well maybe someone can get
ahold of this 4-androsten-3-one and test it out. I know Steraloids.com has the compound: Item number A7098-000

JVK,
The scope of my research is strictly
from a pharmacological standpoint with respect specifically to the vomeronasal organ. The scope of my research
within this realm of pharmacology is typically drug-design, and tweaking of the molecular structures so as to more
selectively or more significantly target a specific neuroreceptor; or, in this case, the VNO. The implications of
this organ, or its physiological response when triggered, I leave to you to interpret.;)
However, I am also
interested to learn of the physiological effects which activation of the VNO evokes; please enlighten me! I was
under the belief that this organ was the most significant in mammalian pheromonal systems; is this a
fallacy?

Unfortunately, steraloids does not have this product in stock (it has to
be made to order). I've asked Trevor if he would be willing to synthesize a small batch affordably or even out of
curiosity! - He has not yet responded, and I eagerly await his notice!
As for
5α-androstan-3-one, look in the original Erox studies. See the following URL:
http://www.erox.com/SixthSense/StoryOne.html, in which the
impulse responses for which various steroidal substances evoke upon the human female VNO is displayed, via a
graphical chart.
PS. Consider that if and when I do obtain this
4-androstenone, I plan to test the impulse response, using an electrogram at a nearby university, utilizing a VNO
tissue sample immersed in a bath of nutrients; an extension of the original Erox study in virtually identical
conditions.:)
PSS. I'm looking into analogues of estratetraenol as well...

You may want to look at the Scientific Evidence page of my domain for
background info. Here's part of one abstract from the conference I will attend next week. Several other abstracts
attest to the lack of concern regarding a functional human VNO. I have no idea whose research you've followed,
since no current data supports extension of your belief to humans, and most of the importance of the VNO to other
mammals is repeatedly being questioned, as is indicated below in female mice.
VOLATILE, SEX-SPECIFIC URINARY
ODORS DETECTED BY THE MAIN OLFACTORY EPITHELIUM AUGMENT FOS EXPRESSION IN THE ACCESSORY OLFACTORY BULB OF FEMALE
MICE
Martel K.L. Botros J. Baum M.J.
Bilateral lesions of the main olfactory epithelium induced by ZnSO4
irrigation of the nares eliminated the ability of volatile male urinary odors to stimulate Fos expression in the AOB
and the MOB, suggesting that the ability of volatile male odors to activate the femaleĀ“s AOB normally depends on
their detection by the main olfactory epithelium as opposed to the vomeronasal organ.

keep us updated of your findings. I mean pheromones don't necessarily have to activate the VNO
substantially to work well (think of Androsterone and Alpha-Androstenol) but the two that do a great job at
activating the VNO according to the Erox studies (Androstadienone and Estratetraenol) are both great mones (well
Estra is new but reviews have been good to great so far). So there MAY be something to activating the VNO for
REAL-LIFE results even if it is not validated by science.
So keep us updated on results you get from
4-androsten-3-one and analogues of estratetraenol both in the lab and in real-life...:thumbsup:

@Archetypical Hybrid (HEC)
Would Vomeropherins A, C, D, E12/N1 & E8/N1 be useful for males?
How do I find the trivial names & CAS no. of the chemicals (if they do exists)?
Thanks.

OE =
olfactory epithelium
CNS = central nervous system
EVG = Electro-vomeronasogram
EOG =
Electro-olfactgram
EFFECTS ON THE EVG
- A, C and D produced
significant effects, that were consistent in all individual cases (males).
- Vomeropherins active in male
subjects produced larger responses than the diluent. B, F and similar concentrations of
olfactants induced significantly magentauced responses in the male VNO.
- Among the vomeropherins, F
produced the most significant differences within the group (females). Here, A induced a small effect that was
significantly different from F.
- In both populations of subjects, active vomeropherins induced receptor
responses having large standard deviations. When the frequency distribution of the effects of A and F was studied in
males and females respectively, we found a bimodal distribution. The significance of this observation is being
studied at this point.
E, a stereoisomer of F, does not stimulate the VNO in female subjects while
F does. This is a demonstration of the specificity of VNO recognition of vomeropherins. In this
regard it is interesting to note that while F is a superior vomeropherin, E generates a stronger
olfactory effect than does F.
EFFECTS ON THE EOG
- In contrast to the sensitivity of the
VNO to vomeropherins, the OE is less sensitive to these substances. This is true for both males and females.
- In this study, B was the only vomeropherin having significant effect in the OE.
- This
finding reveals that at the concentrations used in our study, most vomeropherins are not effective stimulants of the
olfactory receptors, but do have a clear effect on vomeronasal receptors.
REFLEX EFFECTS
-
A and C induced a significant increase in skin temperature in 30 male subjects; however D
induced significant temperature decrease.
- In 30 female subjects, B and F evoked a significant
increase in skin temperature compamagenta to A and C.
- In males, A, C and D
significantly increased alpha cortical activity (D and A evoked the strongest effect).
-
In females, B or F applied to the VNO increased alpha cortical independent of the response of
olfactory receptors.
- The steroid E12/N1 exhibited the best EEG-alpha
activity in men. The steroid E8/N1 exhibited the best EEG-beta activity
in men.
- The steroid E7/N1 exhibited the best EEG-alpha activity in women.
Additionally, it is noted that E7/N1 exhibited excellent organ response, as shown by the EVG
data, in both men and women, but there were gender differences in the CNS (high EEG-alpha in women, high EEG-beta in
men).
Sexual differences were noted in the specificities and effects of two groups of vomeropherins,
A, C and D; and B and F.

Dear good sir,
Please PM me with specific requests; I'm an expert within the discipline of chemical nomenclature and have
access to great quantites of data: ie. Chemical nomenclature, pharmacodynamics, pharmacokinetics, struture activity
relationships, supplier databases, etc.

Alas, you are correct. The
closest relatives which are available with the 4,16-dien substitutions are: 4,16-estradien-3alpha-ol and
4,16-estradien-3-one..
It could probably be made, but would need a custom synthesis (which is about $2,000)..
If either of the three aforementioned possibilites are of interest, contact Bruce to get the ball rolling..
