Sodium glucaspaldrate is an anti-inflammatory and analgesic agent.

MK-571 is a selective, orally active leukotriene D4/E4 (LTD4/E4) receptor antagonist patented by Merck Frosst Canada, Inc. for the treatment bronchoconstriction. In ex vivo models MK-571 competitively antagonizes contractions of guinea pig trachea and ileum induced by leukotriene (LT) D4 and LTE4 and contractions of human trachea induced by LTD4. MK-571 antagonizes bronchoconstriction induced in anesthetized guinea pigs by i.v. LTC4, LTD4, and LTE4 but do not block bronchoconstriction to arachidonic acid. In clinical trials, MK-571 is a potent antagonist of LTD4-induced bronchoconstriction in both normal volunteers and asthmatic patients.

Remeglurant is a selective antagonist of subtype 5 metabotropic glutamate receptors (mGluR5). mGluR5 antagonists have a modulatory role in the control of glutamatergic neurotransmission. This drug was developed for treatment in drug-induced dyskinesia (an involuntary movement disorder). A phase 1 trial was conducted but no further development has been reported since 2016.

GlaxoSmithKline was developing GSK-364735 as a human immunodeficiency virus (HIV) integrase inhibitor. The inhibition of viral DNA integration takes place by interacting at the two-metal binding site within the catalytic center of HIV integrase. GSK-364735 was successfully studied at Phase II in HIV-infected patients; however, adverse liver effects of GSK364735 were recently observed in a long-term preclinical safety study in the monkey and preclude further development of the compound.

Carbon C-13 is a natural, stable isotope of carbon with a nucleus containing six protons and seven neutrons. As one of the environmental isotopes, it makes up about 1.1% of all natural carbon on Earth. Due to differential uptake in plants as well as marine carbonates of 13C, it is possible to use these isotopic signatures in earth science. Biological processes preferentially take up the lower mass isotope through kinetic fractionation. In aqueous geochemistry, by analyzing the δ13C value of carbonaceous material found in surface and ground waters, the source of the water can be identified. Carbon-13 NMR is a valuable tool for the study of organic materials.

CC-220 is a potent cereblon modulating agent that displays anti-proliferative, pro-apoptotic and immunomodulatory activity on sensitive and resistant multiple myeloma cell lines. CC-220 is currently under clinical investigation for systemic lupus erythematosus and multiple myeloma as a single agent, or in combination with dexamethasone in patients who may have previously been exposed to pomalidomide. Comparable to other Cereblon-binding agents, ex vivo treatment of CC-220 on B-cells, T-cells, and monocytes leads to the degradation of the hematopoietic transcription factors Ikaros (IKZF1) and Aiolos (IKZF3). followed by disruption of the multiple myeloma promoting c-Myc/IRF4 axis.

PM-060184 is a new type of marine polyketide isolated from the Madagascan sponge. PM060184 belongs to a new family of tubulin-binding agents. PM060184 is an inhibitor of tubulin polymerization that reduces microtubule dynamicity in cells by 59%. Interestingly, PM060184 suppresses microtubule shortening and growing at a similar extent. PM060184 is able to overcome P-gp mediated resistance in vivo, an effect that could be related to its high binding affinity for tubulin. PM-060184 demonstrated antimitotic properties in human tumor cells lines at subnanomolar concentrations and display a distinct inhibition mechanism on microtubules. An antivascular mechanism is contributing to the antitumor activities of plocabulin. PM-060184 I in phase II clinical trial for the treatment of breast and colorectal cancer.
