Abstract
Anxiety disorders are the most prevalent psychiatric pathology with substantial cost to society, but the existing treatments are often inadequate. This has rekindled the interest in the GABAA-receptor (GABAAR) positive allosteric modulator (PAM) compounds, which have a long history in treatment of anxiety beginning with diazepam, chlordiazepoxide, and alprazolam. While the GABAAR PAMs possess remarkable anxiolytic efficacy, they have fallen out of favor due to a host of adverse effects including sedation, motor impairment, addictive potential and tolerance development. A substantial effort was thus devoted to the design of GABAAR PAMs as anxiolytics with reduced sedative liabilities. Several non-benzodiazepine (BZD) GABAAPAMs progressed to clinical trials (bretazenil, abecarnil, alpidem, and ocinaplon) with alpidem obtaining regulatory approval as anxiolytic, but later withdrawn from market due to hepatotoxicity. Advances in molecular biology gave birth to a host of subtype selective GABAAR-PAMs which suffered from signs of sedation and motor impairment and only three compounds progressed to proof-of-concept studies (TPA-023, AZD7325 and PF-06372865). TPA-023 was terminated due to toxicity in preclinical species while AZD7325 and PF-06372865 did not achieve efficacy endpoints in patients. We highlight a new compound, KRM-II-81, that is an imidazodiazepine selective for GABAAR containing a2/3 and ß3 proteins. In preclinical studies KRM-II-81 produced anxiolytic-like effects but with minimal sedation, respiratory depression, and abuse liability. Thus, KRM-II-81 is a newly discovered, non- BZD anxiolytic compound, which targets a selective population of GABAAR for improved therapeutic gain and reduced side effects.

Here is what I just got from the funding investment group handling the sub company . The replie below was to the posting I sent them by All City Baby
Re: LTListener post# 52589
I agree that the current state of the website is quite awful. Not only does it look amateurish, on the company management page it lists Dr. James Manuso as the CEO. He left the company on September 30, 2018.

Happy new year to you too. Thanks for your email.
Maybe check your sources regarding the management page on the company’s website. Link below for your reference.

Whilst I appreciate the information you have provided, as previously mentioned I’m assisting with raising capital for ResolutionRX so this is where I’m spending my efforts. If you have queries / concerns, or require information for RespireRX, as you are a shareholder, I kindly suggest you speaking with Jeff Margolis directly

Well,
This has been stated in past filings...
"The Company is also engaged in business development efforts (licensing/sub-licensing, joint venture and other commercial structures) with a view to securing strategic partnerships that represent strategic and operational infrastructure additions, as well as cash and in-kind funding opportunities. These efforts have focused on, but have not been limited to, transacting with brand and generic pharmaceutical and biopharmaceutical companies as well as companies with potentially useful contract research, formulation or manufacturing capabilities, significant subject matter expertise and financial resources. No assurance can be given that any transaction will come to fruition and that if it does, that the terms will be favorable to the Company."
Seems like there would be opportunties where some Nasdaq pharma have cash and experience, but maybe less than desired trial results that would be looking for new assets to bring into their world and develop. Could be win-win approach and certainly RSPI lacks significantly in some areas of business development. Could just be reverse merger into Nasdaq shell as well. Seems like this approach would be a better fit for these assets and how they have been non chalant about sticking with the OTC.

Pharmacological modulation of respiratory control: Ampakines as a therapeutic strategy

Abstract
Ampakines are a class of compounds that are positive allosteric modulators of a-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors and enhance glutamatergic neurotransmission. Glutamatergic synaptic transmission and AMPA receptor activation are fundamentally important to the genesis and propagation of the neural impulses driving breathing, including respiratory motoneuron depolarization. Ampakines therefore have the potential to modulate the neural control of breathing. In this paper, we describe the influence of ampakines on respiratory motor output in health and disease. We dissect the molecular mechanisms underlying ampakine action, delineate the diverse targets of ampakines along the respiratory neuraxis, survey the spectrum of respiratory disorders in which ampakines have been tested, and culminate with an examination of how ampakines modulate respiratory function after spinal cord injury. Collectively, the studies reviewed here indicate that ampakines may be a useful adjunctive strategy to pair with conventional respiratory rehabilitation approaches in conditions with impaired neural activation of the respiratory muscles

LT - I've attended many professional conferences where I usually presented. Deals are not made at the conferences, but at the social gatherings after presentations. I see that Lippa and likely most of RSPI are still and will continue attending these conferences, which of course means RSPI is still open for deal making. In addition, researchers present findings before publication which allows Lippa and Cerne to find new approaches, molecules and preclinical results of RSPI's molecules. I suspect they came by their dronabinol platform through a conference social gathering. Lippa is well regarded in neuropharmacology and also a venture capitalist. He took over Cortex obviously recognizing their platform has huge potential. This is hypothetical, whether or not I am correct we will see hopefully soon.

Here’s a repost of my email to Dr Milap Sandhu (msandhu@sralab.org) who will manage CX1739’s clinical trial, funded by the DoD:
Hello Dr Sandhu,
I’m reaching out to you about the recent announcement of a DoD funded study of CX1739. Could you confirm that this is being planned, and if so when will recruitment begin?
I appreciate your time,
Bruno
He promptly replied:
Dear Bruno,
Thank you for reaching out.
Yes, we are planning to initiate a study with CX1739 in individuals with SCI. We are at early stages of this research and it'll take a few months before we begin enrollment.
Are you or someone you know has a spinal cord injury?
Best regards,
Milap

"progress behind the scenes isn't halted"
They just need to get filings done which was supposedly well underway until this "pause" to get off this EM.
But the concern is how many opportunities to attract talent resources, collaborative resources, partnerships, position the company for further fair value investment, build out the shareholder base, position to capitalize on clinical success etc, etc is passing them by??

More press mentions RespireRx Pharmaceuticals, in particular the relevance to spinal cord neuroplasticity, which is, by the way the reason why Dr. Dariusz Nasiek joined the board of director, and provided 100000$ in cash, which he arranged to be backed by 33 million shares of RSPI as a disincentive to further dilution.
And in addition, we should bear in mind that the DoD clinical trial funding is specifically about using the new ampakine CX1739 to support therapeutic hypoxia for recovery of spinal cord damage.
So the pieces of the puzzle are coming together. I would not be surprised to get an update soon on how the setting up of the trial is unfolding, recruiting of subjects, etc.
I posted here earlier this year the name of the Dr who will run the trial, and where. I also confirmed with him that this was indeed underway. Let me try to get in touch with him again.
