Ixazomib (trade name Ninlaro) is a drug for the treatment of multiple myeloma in adults after at least one prior therapy, in combination with lenalidomide and dexamethasone. It is taken by mouth in form of capsules. Common side effects include diarrhea, constipation and low platelet count. Like the older bortezomib (which can only be given by injection), it acts as a proteasome inhibitor, has orphan drug status in the US and Europe. At therapeutic concentrations, ixazomib selectively and reversibly inhibits the protein proteasome subunit beta type-5 (PSMB5) with a dissociation half-life of 18 minutes. This mechanism is the same as of bortezomib, which has a much longer dissociation half-life of 110 minutes; the related drug carfilzomib, by contrast, blocks PSMB5 irreversibly. Proteasome subunits beta type-1 and type-2 are only inhibited at high concentrations reached in cell culture models. PSMB5 is part of the 20S proteasome complex and has enzymatic activity similar to chymotrypsin. It induces apoptosis, a type of programmed cell death, in various cancer cell lines. A synergistic effect of ixazomib and lenalidomide has been found in a large number of myeloma cell lines. The medication is taken orally as a prodrug, ixazomib citrate, which is a boronic ester; this ester rapidly hydrolyzes under physiological conditions to its biologically active form, ixazomib, a boronic acid. Absolute bioavailability is 58%, and highest blood plasma concentrations of ixazomib are reached after one hour. Plasma protein binding is 99%.

Valrubicin is a semisynthetic analog of the anthracycline doxorubicin, and is administered by infusion directly into the bladder. Valrubicin is an anthracycline that affects a variety of inter-related biological functions, most of which involve nucleic acid metabolism. It readily penetrates into cells, where after DNA intercalation, it inhibits the incorporation of nucleosides into nucleic acids, causes extensive chromosomal damage, and arrests cell cycle in G2. Although valrubicin does not bind strongly to DNA, a principal mechanism of its action, mediated by valrubicin metabolites, is interference with the normal DNA breaking-resealing action of DNA topoisomerase II. Valrubicin is FDA approved drug, sold under the trade name Valstar.

Fluazuron (N-[[4-chloro-3-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxyphenyl]carbamoyl]-2,6-difluorobenzamide, trade name Acatak) is an insect growth regulator belonging to the class of benzoyl phenyl urea derivatives, a class of chitin synthesis inhibitors. Fluazuron specifically interferes with chitin formation in ticks during engorgement, molt, and hatching. The substance is intended for tick control in beef cattle applied topically as a pour-on for use at single dose levels of 1.5 and 2.5 mg/kg BW with a possible additional treatment after 3 to 6 months.

MLN8054 is a reversible, ATP competitive inhibitor of recombinant Aurora A, developed by Millennium Pharmaceuticals. MLN8054 was tested in phase I clinical trials against advanced solid tumors. Reversible somnolence probably due to off-target inhibition of alpha-1 subunit of GABA-A receptor was dose limiting and prevented achievement of plasma concentrations predicted necessary for target modulation.

Fenretinide (4-HPR) is an orally-active synthetic phenylretinamide analogue of retinol (vitamin A) with potential antineoplastic and chemopreventive activities. Fenretinide binds to and activates retinoic acid receptors (RARs), thereby inducing cell differentiation and apoptosis in some tumor cell types. This agent also inhibits tumor growth by modulating angiogenesis-associated growth factors and their receptors and exhibits retinoid receptor-independent apoptotic properties. Phase III clinical trial data has suggested that fenretinide reduces breast cancer relapse in pre-menopausal women. Fenretinide is the most studied retinoid in breast cancer chemoprevention clinical trials due to its selective accumulation in breast tissue and its favorable toxicological profile. This agent showed a significative reduction of the incidence of second breast tumors in premenopausal women confirmed after 15-year followups. Fenretinide, a drug being developed by Sirion Therapeutics, slowed the progression of advanced dry age-related macular degeneration (AMD) by 45 percent for people receiving a higher dose of the treatment in a Phase II clinical trial. Sirion has been granted a Fast Track designation for the treatment by the FDA. Fenretinide is in phase II clinical trials for the treatment of B-cell lymphoma, chronic lymphocytic leukemia. It is also in phase I clinical trials for the treatment of cystic fibrosis.

Sinigrin is a glucosinolate that is found in plants of the Brassicaceae family. It is enzymatically degraded to allyl isothiocyanate which is responsible for the taste of mustard and horseradish. Allyl isothiocyanate has been identified as having anti-cancer effects; although sinigrin, itself, is not bioactive. Sinigrin has also been shown to have anti-inflammatory activity, antibacterial activity, antifungal activity, antioxidant activity, and wound healing activity.

Yangonin is a natural kavalactone found in the kava plant. Yangonin has been shown to possess binding affinity for the cannabinoid receptor CB1, where it behaves as an agonist. Yangonin also inhibits anchorage-dependent and independent growth of bladder cancer cell lines through induction of autophagic cell death. Yangonin displays marked in vitro toxicity on human hepatocytes with approximately 40% reduction in viability based on an ethidium bromide assay and FDA advises against the use of kava in food due to the potential risk of severe liver damage.

Piperlongumine is a natural bioactive small molecule isolated from the Piper longum Linn plant. This compound is easily available, inexpensive, and has therapeutic effects against cancer, heart disease, intestinal diseases, diabetes, obesity, joint pain and other conditions in Chinese Herbal and Indian Ayurvedic medicine. As a primary constituent of Piper longum Linn, PLM has been reported to exert effects against cancer, platelet aggregation, atherosclerosis, diabetes and inflammation. Mechanistic investigations have found that PLM selectively augments ROS levels in tumor cells and regulates downstream signaling, including NF-κB, MAPK, and STAT3 pathways, in several other cell types.

Evans Blue (EBD) is an azo dye which has a very high affinity for serum albumin. It can be useful in physiology in estimating the proportion of body water contained in blood plasma. Evans Blue Dye is widely used to study blood vessel and cellular membrane permeability as it is non-toxic, it can be administered as an intravital dye and it binds to serum albumin – using this as its transporter molecule. The EBD–albumin conjugate (EBA) can be: (i) identified macroscopically by the striking blue colour within tissue; (ii) observed by red auto-fluorescence in tissue sections examined by fluorescence microscopy; and (iii) assessed and quantified by spectrophotometry for serum samples, or homogenised tissue. has recently been utilised in mdx mice to identify permeable skeletal myofibres that have become damaged as a result of muscular dystrophy. EBD has the potential to be a useful vital stain of myofibre permeability in other models of skeletal muscle injury and membrane-associated fragility. Evans Blue is a potent inhibitor of L-glutamate uptake into synaptic vesicles. It also inhibits AMPA and kainate receptor-mediated currents (IC50 values are 220 and 150 nM respectively). P2X-selective purinoceptor antagonist.

Aceglatone (Glucaron/ 2.5-Di-O-acetyl-D-glucaro-1,4:6,3-dilactone/ DAGDL ) is a non-toxic natural inhibitor of beta-glucuronidase. Is an antineoplastic drug available in Japan, which is used for preventive therapy after preservative operation against bladder cancer.
