Class (Stereo):
CHEMICAL (ACHIRAL)

Iosimide is synthetic, nonionic, monomeric contrast medium patented by Schering A.-G. In clinical trial Iosimide exhibited no differences in comparison with Ioxaglate with respect to the contrast, the neurological status or the liver or renal tolerance. In examining cardiovascular tolerance there is only a slight tendency toward liver changes with Iosimide. Examination of the general tolerance, however, shows a statistically significant lower incidence of sensation of heat and pain with iosimide than with ioxaglate.
Lomofungin, a natural product compound first isolated from the soil-dwelling Gram-positive bacteria Streptomyces lomodensis. Lomofungin has a broad antibacterial and antifungal spectrum, being active against gram-positive and gram-negative bacteria, yeasts, and other fungi. It prevents RNA synthesis by a direct interaction with the bacterial DNA-dependent ribonucleic acid (RNA) polymerase and not with the template or substrate. Lomofungin was identified as an inhibitor of botulinum neurotoxin light chain protease and as a potential therapeutic for myotonic dystrophy type 1. Lomofungin inhibited HIV-1 replication in peripheral blood mononuclear cells.

INN:repromicin

Class (Stereo):
CHEMICAL (ABSOLUTE)

Repromicin is a compound that was reported in the literature in the 1990’s. Repromicin derivatives were found to have potent antibacterial activity against the Gram-negative pathogen Pasteurella multocida and Pasteurella heamolytica (in vitro and in vivo). Subcutaneous administration (single dose) in animals was found to control induced pasteurellosis (in swine) and induced respiratory disease (in cattle).

CHEMICAL (ABSOLUTE)

Inocoterone acetate (USAN) (also known as RU-38882, RU-882) is the acetate ester of inocoterone a steroid-like nonsteroidal antiandrogen (NSAA) that was developed for topical administration to treat acne but was never marketed. Inocoterone acetate is actually not a silent antagonist of the androgen receptor but rather a weak partial agonist, similarly to steroidal antiandrogens like cyproterone acetate. In this double-blind study of 126 male subjects with acne, a topical solution of the antiandrogen inocoterone produced a modest but statistically significant reduction in the number of inflammatory acne lesions.

INN:piposulfan

Class (Stereo):
CHEMICAL (ACHIRAL)

Piponulfan is neutral, difunctional alkylating derivative of piperazine. This agent was studied for their antineoplastic activity. Piposulfan has been found to be active against the following mouse tumors: sarcoma 180, carcinoma 755, and leukemia 1210. In patients with polycythemia piposulfan produced a response rate similar to that seen with pipobroman, busulfan, and triethylene melamine. However, piposulfan produces noticeably less toxicity than standard recommended doses of either busulfan or triethylene melamine. Various degrees of therapeutie remissions were seen in patients with malignant lymphomas, acute and chronic leukemia, multiple myeloma, adenocarcinomas, epidermoid carcinomas, and various types of sarcomas. The most common adverse reactions to piposulfan involved the hematopoietic (bone marrow depression) and gastrointestinal organs.

INN:pentamorphone

Class (Stereo):
CHEMICAL (ABSOLUTE)

Pentamorphone was developed as a highly potent opioid with rapid onset and short duration of action that has been reported to produce analgesia with limited depression of ventilation. Pentamorphone participated in a clinical trial for the management of postoperative pain. However, no acute cardiorespiratory changes were observed. The drug was ineffective for treating acute postoperative pain after major surgery. In addition, was shown that pentamorphone, 10 micrograms/kg, does not seem to offer any significant advantage over opioids currently used for anesthesia in patients undergoing elective coronary artery bypass grafting (CABG). That is why its further development was discontinued.

Conditions:

N,N-Dimethyl-5-Methoxytryptamine (aka 5-MeO-DMT) is a psychedelic of the tryptamine class. It is found in a wide variety of plant species, and a single psychoactive toad species, the Colorado River toad. Like its close relatives DMT and bufotenin (5-HO-DMT), it has been used as an entheogen in South America. It can also be found in the dart poison traditionally used by the Yanoama Indians of Upper Orinoco. It acts as a non-selective serotonin (5-HT) agonist. -MeO-DMT is O-demethylated by polymorphic cytochrome P450 2D6 (CYP2D6) to an active metabolite, bufotenine. 5-MeO-DMT is classified as a controlled substance in China, Australia, Sweden, Turkey, and the USA.

Conditions:

Androsterone, a neurosteroid, acts as a positive allosteric modulator of GABA(A) receptors, that can cross into the brain and could have effects on brain function. It was discovered, that the association of beta subunits with alpha subunits GABA(A) receptor affects the sensitivity of glycine receptors to androsterone. In spite of that, androsteron is considered as an inactive metabolite of testosterone. In addition, was studied that androsterone possessed anticonvulsant properties. Although of low potency, the androsterone was present in high abundance and was able to represent endogenous modulator of seizure susceptibility.

Class (Stereo):
CHEMICAL (ACHIRAL)


Muscimol is one of the principal psychoactive constituents of Amanita muscaria and related species of mushroom. Muscimol is a potent, selective agonist for the GABAAreceptors and displays sedative-hypnotic, depressant and hallucinogenic psychoactivity. The effects of the Amanita mushrooms begin 30–120 minutes after consumption and the effects last for 5–10 hours. Some of the desired effects include euphoria, dream-like (lucid) state of mind, out-of-body experiences, and synesthesia. Neutral effects include dizziness, clumsiness, the feeling of increased physical strength, loss of equilibrium, and a glassy-eyed stare. Calming effects may be felt, but completely opposite effects such as extreme energy bursts have been described. Negative effects include mild to moderate nausea, stomach discomfort, increased salivation, and muscle twitching or tremors. In large doses, strong dissociation or delirium may be felt.
