Steroid Biochem., 14, 457 (1981), Choi, M., et al.: Steroids, 65, 54 (2000); Haeberlin, B. et al.: Pharm Res., 10, 1553 (1993);

gamma-Bufotalin is a bufadienolide compound, which is a type of steroid. It is sourced from toad venom, specifically from the parotoid glands of toads belonging to the Bufonidae family. This compound exhibits its mode of action primarily through inhibition of cellular ion pumps, particularly the Na⁺/K⁺-ATPase, leading to an increase in intracellular calcium levels. This mechanism induces apoptosis in certain cancer cell lines, providing a potential pathway for therapeutic intervention. Research into gamma-Bufotalin explores its potential applications in oncology, given its ability to trigger apoptosis and inhibit proliferation in tumor cells. Additionally, it has been studied for its anti-inflammatory properties and interaction with various cellular pathways. While the therapeutic potential is promising, ongoing investigations are required to fully understand the pharmacodynamics, toxicity, and efficacy of gamma-Bufotalin in clinical settings.

Hydrocortisone acetate is a synthetic corticosteroid, which is a product derived from the modification of natural adrenal cortex hormones. It functions as an anti-inflammatory and immunosuppressive agent through its interaction with glucocorticoid receptors, leading to the modulation of gene expression involved in immune and inflammatory responses. This interaction inhibits the release of pro-inflammatory mediators and reduces the permeability of capillaries, thereby diminishing inflammation and immune activity. Hydrocortisone acetate is extensively used in medical settings to manage conditions requiring suppression of inflammatory and immune responses. It is applied in the treatment of various dermatological conditions, including eczema and psoriasis, as well as allergic reactions. Additionally, it serves as a therapeutic agent in the management of adrenal insufficiency and as an adjunct treatment for other inflammatory disorders. Its pharmacological efficacy and mechanism of action render it an essential component in the arsenal of therapeutic agents targeting inflammatory and autoimmune diseases.

Polyphyllin D is a natural compound, which is a steroidal saponin extracted from the rhizome of Paris polyphylla, a traditional Chinese medicinal plant. It exhibits significant biological activities and has garnered interest for its potential therapeutic applications. Polyphyllin D exerts its effects primarily through the disruption of cellular processes, including the induction of apoptosis, modulation of the cell cycle, and inhibition of angiogenesis. It achieves these actions by influencing multiple molecular pathways, such as the mitochondrial apoptotic pathway and autophagy regulation. Polyphyllin D is being extensively studied for its potential as an anticancer agent. In preclinical studies, it has demonstrated efficacy against various cancer cell lines, including lung, breast, and ovarian cancers. Its ability to selectively target cancer cells while sparing normal cells underscores its promise as a therapeutic candidate. The compound has also shown potential in overcoming drug resistance in certain cancer treatments, making it an area of interest for further investigation. As research advances, understanding the full spectrum of Polyphyllin D's mechanisms and applications continues to evolve, offering insights into its role in future oncology treatments.
