ST-168 is a potent inhibitor of PI3K and MEK. ST-168 displays improved PI3K and MEK1 isoform inhibition. ST-168 demonstrated a 2.8-, 2.7-, 23-, and 2.5-fold improved inhibition toward the PI3Kα, PI3Kβ, PI3Kδ, and PI3Kγ isoforms and a 2.2-fold improvement
5α-Androst-16-en-3α-ol is a steroid pheromone that has been found in boar testes and human male axillary sweat and has diverse biological activities.1,2It enhances GABA-activated currents in primary mouse cerebellar granule cells (EC50= 0.4 μM).25α-Androst-16-en-3α-ol (0.1-1 μM) increases the amplitude of GABA-activated currents in HEK293 cells expressing human α1β2γ2and α2β2γ2subunit-containing GABAAreceptors.In vivo, 5α-androst-16-en-3α-ol (5-10 mg kg) decreases immobility time in the forced swim test in mice. It increases time spent in the open arms of the elevated plus maze in mice, indicating anxiolytic-like activity, when administered at doses ranging from 30 to 50 mg kg. 5α-Androst-16-en-3α-ol protects against seizures induced by pentylenetetrazole or electroshock in mice (ED50s = 48.9 and 21.9 mg kg, respectively). 1.Brooksbank, B.W., Brown, R., and Gustafsson, J.A.The detection of 5α-androst-16-en-3α-ol in human male axillary sweatExperientia30(8)864-865(1974) 2.Kaminski, R.M., Marini, H., Ortinski, P.I., et al.The pheromone androstenol (5α-androst-16-en-3α-ol) is a neurosteroid positive modulator of GABAA receptorsJ.

Antitubercular agent-16 (Compound 5q) is a potent antitubercular agent exhibiting high efficacy against various strains of M. tuberculosis, including H37Rv, CF16, CF61, CF76, CF152, and CF161, with MIC 90 values ranging from 0.40 to 23.51 μg mL. Notably, Antitubercular agent-16 demonstrates minimal cytotoxicity towards macrophages and pulmonary fibroblasts, further highlighting its potential as a therapeutic agent [1].
5α-Androst-16-en-3-one, a mammalian pheromone present in boar saliva, plays a crucial role in facilitating social and sexual interactions by acting as a volatile chemical cue. It is utilized to prime sows in estrus for mating or artificial insemination, underscoring its significance in reproductive behavior. Additionally, this compound is detected in human sweat and urine, where it is involved in studies concerning receptor-mediated odorant detection and the genetic foundations of anosmias, thereby broadening its scope of relevance beyond the animal kingdom.
