Ibrutinib is an orally bioavailable Bruton's tyrosine kinase (BTK) inhibitor indicated for the treatment of mantle cell lymphoma (MCL) patients that previously received at least one therapy. The drug was jointly developed by Janssen Biotech and Pharmacyclics. Ibrutinib selectively binds to Cys-481 residue in the allosteric inhibitory segment of BTK (TK/SH1 domain), and irreversibly blocks its enzymatic activity thus preventing B-cell activation and signaling, totally blocking the B-cell receptor and cytokine receptor pathways. This leads to an inhibition of the growth of malignant B cells that overexpress BTK. Apart from mantle cell lymphoma Ibrutinib is approved for the treatment of chronic lymphocytic leukemia and Waldenstrom Macroglobulinemia.
Riociguat is a potent, oral stimulator of soluble guanylate cyclase (sGC). It is the first member of a novel class of compounds, being developed by Bayer as an investigational, oral treatment to target a key molecular mechanism underlying pulmonary hypertension (PH). Riociguat demonstrated robust clinical efficacy in two separate PH indications: chronic thromboembolic pulmonary hypertension (CTEPH) and pulmonary arterial hypertension(PAH). Riociguat works in two ways: it sensitizes sGC to endogenous NO by stabilizing the NO-sGC binding and directly stimulates sGC via a different binding site, independently of NO. Riociguat stimulates the NO-sGC-cGMP pathway and leads to increased generation of cGMP with subsequent vasodilation. Through this unique way of working, riociguat decreases blood pressure within the pulmonary arteries that take blood from the heart to the lungs, reducing pressure on the heart leading to improved patient outcomes.
Luliconazole (trade names Luzu, Lulicon) is an imidazole antifungal drug. As a 1% topical cream, It is indicated for the treatment of athlete's foot, jock itch, and ringworm caused by dermatophytes such as Trichophyton rubrum, Microsporum gypseum and Epidermophyton floccosum. Luliconazole is an antifungal that belongs to the azole class. Although the exact mechanism of action against dermatophytes is unknown, luliconazole appears to inhibit ergosterol synthesis by inhibiting the enzyme lanosterol demethylase. Inhibition of this enzyme’s activity by azoles results in decreased amounts of ergosterol, a constituent of fungal cell membranes, and a corresponding accumulation of lanosterol. Pharmacokinetic and safety results from phase 1 studies in patients with onychomycosis have demonstrated high concentrations of luliconazole within the nail plates of the great toe and have shown that this agent is well tolerated when administered as a 10% solution.
Afatinib is a anilino-quinazoline derivative and irreversible antagonist of the receptor tyrosine kinase epidermal growth factor receptor family, with antineoplastic activity. Afatinib selectively and covalently binds to and inhibits the epidermal growth factor receptors 1 (ErbB1; EGFR), 2 (ErbB2; HER2), and 4 (ErbB4; HER4), and certain EGFR mutants, including those caused by EGFR exon 19 deletion mutations or exon 21 (L858R) mutations. This may result in the inhibition of tumor growth and angiogenesis in tumor cells overexpressing these kinases. Additionally, afatinib inhibits the EGFR T790M gatekeeper mutation which is resistant to treatment with first-generation EGFR inhibitors. EGFR, HER2 and HER4 are RTKs that belong to the EGFR superfamily; they play major roles in both tumor cell proliferation and tumor vascularization and are overexpressed in many cancer cell types. Afatinib is a substrate and an inhibitor of P-gp and of the transporter BCRP. Co-administration of P-gp inhibitors can increase afatinib exposure while co-administration of chronic P­gp inducers can decrease afatinib exposure.

Canagliflozin (INN, trade name Invokana or Sulisent) is a drug of the gliflozin class. It was developed by Mitsubishi Tanabe Pharma and is marketed under license by Janssen, a division of Johnson & Johnson. Canagliflozin is an antidiabetic drug used to improve glycemic control in people with type 2 diabetes. Sodium-glucose co-transporter 2 (SGLT2), expressed in the proximal renal tubules, is responsible for the majority of the reabsorption of filtered glucose from the tubular lumen. Canagliflozin is an inhibitor of SGLT2. By inhibiting SGLT2, canagliflozin reduces reabsorption of filtered glucose and lowers the renal threshold for glucose (RTG), and thereby increases urinary glucose excretion. In extensive clinical trials, canagliflozin produced a consistent dose-dependent reduction in HbA1c of 0.77% to 1.16% when administered as monotherapy, combination with metformin, combination with metformin and a sulfonylurea, combination with metformin and pioglitazone, and in combination with insulin from a baselines of 7.8% to 8.1%, in combination with metformin, or in combination with metformin and a sulfonylurea. When added to metformin, canagliflozin 100 mg was shown to be non-inferior to both sitagliptin 100 mg and glimepiride in reductions on HbA1c at one year, whilst canagliflozin 300 mg successfully demonstrated statistical superiority over both sitagliptin and glimiperide in HbA1c reductions. Secondary efficacy endpoint of superior body weight reduction and blood pressure reduction (versus sitagliptin and glimiperide)) were observed as well. Canagliflozin produces beneficial effects on HDL cholesterol whilst increasing LDL cholesterol to produce no change in total cholesterol.

Pomalidomide is a derivative of thalidomide marketed by Celgene, an analogue of thalidomide, is an immunomodulatory agent with antineoplastic activity. In in vitro cellular assays, pomalidomide inhibited proliferation and induced apoptosis of hematopoietic tumor cells. Additionally, pomalidomide inhibited the proliferation of lenalidomide-resistant multiple myeloma cell lines and synergized with dexamethasone in both lenalidomide-sensitive and lenalidomide-resistant cell lines to induce tumor cell apoptosis. Pomalidomide enhanced T cell- and natural killer (NK) cell-mediated immunity and inhibited production of pro-inflammatory cytokines (e.g., TNF-α and IL-6) by monocytes. Pomalidomide demonstrated anti-angiogenic activity in a mouse tumor model and in the in vitro umbilical cord model.

Vismodegib (trade name Erivedge) is a drug for the treatment of basal-cell carcinoma (BCC). It was approved by FDA on January 30, 2012 and by the European Commission on 12 July 2013, for the treatment of adult patients with symptomatic metastatic BCC, or locally advanced BCC inappropriate for surgery or radiotherapy. The drug is also undergoing clinical trials for metastatic colorectal cancer, small-cell lung cancer, advanced stomach cancer, pancreatic cancer, medulloblastoma and chondrosarcoma as of June 2011. The substance acts as a cyclopamine-competitive antagonist of the smoothened receptor (SMO) which is part of the hedgehog signaling pathway. The Hedgehog signaling pathway plays an important role in tissue growth and repair; aberrant constitutive activation of Hedgehog pathway signaling and uncontrolled cellular proliferation may be associated with mutations in the Hedgehog-ligand cell surface receptors PTCH and SMO. SMO inhibition causes the transcription factors GLI1 and GLI2 to remain inactive, which prevents the expression of tumor mediating genes within the hedgehog pathway. This pathway is pathogenetically relevant in more than 90% of basal-cell carcinomas.
Pasireotide is a synthetic long-acting cyclic hexapeptide with somatostatin-like activity. It is marketed as a diaspartate salt called Signifor, indicated for the treatment of adult patients with Cushing’s disease for whom pituitary surgery is not an option or has not been curative. SIGNIFOR is an injectable cyclohexapeptide somatostatin analogue. Pasireotide exerts its pharmacological activity via binding to somatostatin receptors (ssts). Pasireotide binds and activates the hsst receptors resulting in inhibition of ACTH secretion, which leads to decreased cortisol secretion.

Avanafil is a PDE5 inhibitor approved for erectile dysfunction by FDA and by EMA. Avanafil is known by the trademark names Stendra and Spedra and was developed by Vivus Inc. Avanafil selectively inhibits PDE5, thus inhibiting the degradation of cyclic guanosine monophosphate (cGMP) found in the smooth muscle of the corpus cavernosa of the penis. The physiologic mechanism of erection of the penis involves release of nitric oxide (NO) in the corpus cavernosum during sexual stimulation. NO then activates the enzyme guanylate cyclase, which results in increased levels of cGMP, producing smooth muscle relaxation in the corpus cavernosum and allowing inflow of blood. Avanafil has no direct relaxant effect on isolated human corpus cavernosum, but enhances the effect of NO by inhibiting PDE5, which is responsible for degradation of cGMP in the corpus cavernosum. Because sexual stimulation is required to initiate the local release of nitric oxide, the inhibition of PDE5 has noeffect in the absence of sexual stimulation. The advantage of avanafil is that it has very fast onset of action compared with other PDE5 inhibitors. It is absorbed quickly, reaching a maximum concentration in about 30–45 minutes. About two-thirds of the participants were able to engage in sexual activity within 15 minutes.
