Cis-Tadalafil is a potent inhibitor of phosphodiesterase 5, which is used to treat erectile dysfunction (ED) and primary pulmonary hypertension (PPH). It works by increasing blood flow to the penis, allowing men with ED to achieve and maintain an erection. Cis-Tadalafil is also used to treat symptoms of prostatic hyperplasia (enlarged prostate) in men. This drug has been shown to be effective in treating PPH by reducing pulmonary arterial pressure and improving exercise capacity. Cis-Tadalafil belongs to the carboline class of drugs and is a phosphodiesterase 5 inhibitor that selectively inhibits cGMP-specific phosphodiesterase type 5 (PDE5). This drug has been shown to be highly effective in treating both ED and PPH with minimal side effects.

(S)-Rabeprazole sodium is an anticancer drug that acts as a kinase inhibitor. It is an analog of Rabeprazole and has been shown to inhibit the growth of cancer cells in vitro and in vivo. (S)-Rabeprazole sodium inhibits the activity of kinases, which are enzymes that play a key role in cell signaling pathways. This inhibition leads to apoptosis, or programmed cell death, in cancer cells. (S)-Rabeprazole sodium has been tested against various types of cancer, including Chinese hamster ovary cells and tumor xenografts in mice. It has also been shown to inhibit elastin degradation, which is important for preventing metastasis of cancer cells. (S)-Rabeprazole sodium may be a promising candidate for the development of new anticancer drugs that target specific kinases and proteins involved in cancer cell growth and survival.
