Tadalafil (market name “Cialis” or “Adcirca”) was developed by American pharmaceutical company Lilly. It is a kind of PDE5 inhibitor used for the treatment of erectile dysfunction, benign prostatic hypertrophy and pulmonary arterial hypertension.The effect of Tadalafil is relaxing the blood vessels muscles and increasing the blood flow into the corpus cavernosum. Studies show that Cialis works very quickly, taking effect in around 15-20 minutes, and has a prolonged effect that can last for up to 36 hours. T1/2 is 17.5h. Tadalafil is one of the two new PDE5 inhibitors launched for the oral treatment of male erectile dysfunction. Tadalafil is a b-carboline derivative and it is structurally distinct from vardenafil (Levitraw) and sildenafil (Viagraw), both of which are PDE5 inhibitors based on a fused pyrimidine core structure.

Phenacetin, a widely used analgesic and antipyretic drug, was first synthesized in 1878 by Harmon Northrop Morse. Derived from p-phenetidine, phenacetin's structure was confirmed through chemical analysis and testing. By 1887, it was introduced into the market by Bayer and quickly became popular due to its effectiveness in reducing pain and fever. Its chemical composition and pharmacological properties have made it a significant compound in medicinal chemistry. Phenacetin was primarily used to treat mild to moderate pain, such as headaches, toothaches, and menstrual cramps. Its antipyretic properties also made it effective in reducing fever. For many years, it was a common ingredient in over-the-counter pain relief medications and was often combined with other analgesics like aspirin or caffeine to enhance its effects. Phenacetin was frequently used in combination drugs, such as APC (aspirin, phenacetin, and caffeine) tablets, which were popular for treating pain and inflammation. These combinations provided synergistic effects, improving the overall efficacy of pain relief medications.

Sodium cyanoborohydride (NaBH3CN) is a selective reducing agent used for a variety of chemical reductions, including aldehyde, ketones, acetals, epoxides, oximes, enamines, reductive aminations of aldehydes and ketones, and reductive alkylations of amines and hydrazines. The utility of sodium cyanoborohydride as a reducing agent is greatly enhanced by its stability under acid conditions, and its solubility in aprotic solvents. Sodium cyanoborohydride is a milder and more selective reducing agent than sodium borohydride. Sodium cyanoborohydride is a weaker and more-selective reducing agent than sodium borohydride because of the electron-withdrawing effect of the cyano group. It has the further advantage that it is stable in acid to pH = 3 and can be employed to effect reductions in the presence of functional groups that are sensitive to the more-basic conditions of reduction with sodium borohydride. Aldehydes and ketones are unaffected by sodium cyanoborohydride in neutral solution, but they are readily reduced to the corresponding alcohol at pH=3-4 by way of the protonated carbonyl group. By previous exchange of the hydrogens of the borohydride for deuterium or tritium, by reaction with D2O or tritiated water, an efficient and economical route is available for deuteride or tritiide reduction of aldehydes and ketones. Sodium Cyanoborohydride is a commonly used as a reagent in the reductive amination of aldehydes and ketones and in the reductive alkylation of amines. It is also used in the synthesis of a novel phenolate-bridged dilanthanum(III) complex of interest as a model for metalloproteins as well as for its importance in basic and applied chemistry.

Sodium triacetoxyborohydride, also known as sodium triacetoxyhydroborate, commonly abbreviated STAB, is a white hygroscopic solid that emits hydrogen gas when hydrolysed in water, which is flammable. It is a milder reducing agent than sodium borohydride or even sodium cyanoborohydride. Even sodium cyanoborohydride is a milder reducing agent than sodium borohydride, and is particularly suitable for the reductive amination of aldehydes and ketones. It can reduce aldehydes but not most ketones. Sodium triacetoxyborohydride is a mild reagent that exhibits remarkable selectivity as a reducing agent. It reduces aldehydes but not ketones; however, beta-hydroxyketones can be reduced selectively to give 1,3-trans diols.The steric and the electron-withdrawing effects of the three acetoxy groups stabilize the boron-hydrogen bond and are responsible for its mild reducing properties. It can also be used in the reductive alkylation of secondary amines in aldehyde-bisulfite adducts.

5-Methoxytryptamine (5-MT), also known as mexamine, is a tryptamine derivative closely related to the neurotransmitters serotonin and melatonin. 5-MT has been shown to occur naturally in the body in low levels. It is biosynthesized via the deacetylation of melatonin in the pineal gland. The protective effect of 5- methoxytryptamine (a metabolite of melatonin) in human keratinocytes against ultraviolet B (UVB) radiation was studied. Melatonin and its metabolites ameliorate ultraviolet B-induced damage in human epidermal keratinocytes. In terms of application, 5-Methoxytryptamine exhibits several significant properties. One of its primary areas of interest is its role in neuroscience and psychiatry. It is known to interact with serotonin receptors in the brain, particularly the 5-HT2A receptor, which is associated with mood regulation and perception. In addition to its neuropharmacological effects, 5- Methoxytryptamine has been investigated for its role in psychotropic research. It is often used as a research tool to understand the mechanisms of psychoactive substances and their interactions with neurotransmitter systems. Moreover, 5-Methoxytryptamine has been explored in the context of entheogenic research, which examines the use of psychoactive substances in spiritual or religious practices. Its psychoactive effects and interactions with serotonin receptors contribute to its interest in studies on altered states of consciousness and their therapeutic applications. The chemical synthesis of 5- Methoxytryptamine typically involves the introduction of a methoxy group into the tryptamine structure. This process is often achieved through a series of chemical reactions that modify the indole ring of tryptamine. Characterization of the synthesized compound is performed using analytical techniques such as high-performance liquid chromatography (HPLC) and mass spectrometry (MS), which ensure the purity and identity of the final product. In summary, 5- Methoxytryptamine is a chemically intriguing compound with applications spanning neuropharmacology, psychiatry, and psychotropic research. Its interaction with serotonin receptors and potential therapeutic effects make it a subject of ongoing interest in the study of neurotransmitter systems and psychoactive substances.

Tryptamine is a monoamine alkaloid that can be synthesized by decarboxylation of the amino acid tryptophan. Notably, tryptamine can be found in fungi, plants, Amphibia, animals, and microbes. Tryptamine has an indole ring structure and a fused double ring that is composed of a benzene ring and a pyrrole ring, linked to an amino group by 2- carbon side chain. The indole ring is the vital nucleus of many complex natural products that have significance in drug discovery as well as some synthetic and non-synthetic drugs that are based on tryptamine skeleton. The chemical’s distinct structure is an approximation to the neurotransmitter serotonin as well-known drugs and hallucinogens. Tryptamine’s significance as psychedelic drugs, neuromodulator, and neurotransmitter is well understood due to its presence in mammalian brain in small amounts.
