Sabizabulin (ABI-231) is a potent, orally bioavailable α- and β-tubulin inhibitor that is active against melanoma and prostate cancer cell lines. Sabizabulin inhibits tumor growth and metastatic phenotypes of cervical cancer cells by targeting HPV E6 and E7 and is also being studied in prostate cancer.

BPDA2 is a highly selective and competitive SHP2 inhibitor, exhibiting IC50 values of 92.0 nM for SHP2, and 33.39 μM and 40.71 μM for SHP1 and SHP1B, respectively. This compound effectively downregulates mitogenic and cell survival signaling, including reducing expression of receptor tyrosine kinases (RTKs). Furthermore, BPDA2 suppresses SHP2-mediated signaling, leading to the inhibition of breast cancer cell phenotypes [1].

BRD5631 is an autophagy enhancer that operates through an mTOR-independent pathway. It influences several cellular disease phenotypes associated with autophagy, such as protein aggregation, cell survival, bacterial replication, and inflammatory cytokine production. BRD5631 can serve as a valuable tool for studying the role of autophagy in cellular homeostasis and disease. [1].

Equisetin, an N-methylserine-derived acyl tetramic acid isolated from the terrestrial fungus Fusarium equiseti NRRL 5537, functions as a Quorum-sensing inhibitor (QSI) that specifically attenuates QS-regulated virulence phenotypes in P. aeruginosa, presenting a potent lead for treating P. aeruginosa infections without hindering bacterial growth. This tetramate-containing natural product possesses antibiotic and cytotoxic properties, effectively inhibiting the growth of Gram-positive bacteria and HIV-1 integrase activity, yet it does not impact Gram-negative bacteria.

G923-0271 is a TDP-43 inhibitor that improves disease phenotypes in TDP-43 nematode models and reduces the overexpression of human TDP-43 at the cellular level, making it useful for studying diseases such as amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD).

GTCpFE, a compound synthesized from Dimethyl fumarate (DMF) and Aspirin (ASA), inhibits IKKα β in the NF-κB pathway, exhibiting anti-inflammatory activity by preventing p65 from entering the nucleus. It selectively inhibits cancer stem cell (CSC) activity by reducing the growth of mammospheres and the expression of the CD44+CD24- immune phenotype. Furthermore, GTCpFE targets breast cancer stem cells, crucial in aggressive cancer phenotypes that depend on NFκB and PGE2.

ABCA1 inducer 1, a non-lipid inducer of ABCA1, enhances ABCA1 expression in E3 4FAD mice expressing human APOE 3 4, augments the lipidation of apolipoprotein (APOE), and reverses various Alzheimer's disease (AD) phenotypes without increasing triglycerides.

Antibacterialagent 247 (compound 30b) is a bacterium (bacterial) antagonist that significantly inhibits the formation of biofilms by Pseudomonas aeruginosa (IC50=5.8 μM) and various virulence phenotypes. It also enhances the antibacterial activity of combined treatments with tobramycin and polymyxin B.

SBI-183 is an orally active QSOX1 inhibitor (Kd: 20 μM). It can inhibit the proliferation and invasion phenotypes of renal carcinoma cell lines, triple-negative breast cancer cell lines, lung adenocarcinoma cell lines, and pancreatic ductal adenocarcinoma. In vivo, SBI-183 suppresses tumor growth in two human renal cell carcinoma xenograft mouse models.

KK181N1 is an effective inhibitor of the karrikin (KAR) receptor KAI2. It binds non-covalently to the catalytic pocket of KAI2 and selectively inhibits KAR-induced phenotypes in Arabidopsis.

ZH8965 is an orally active TAAR1-Gs/Gq agonist (EC50: 6.1/14.8 nM) that shows efficacy in alleviating antipsychotic-like phenotypes and cognitive deficits in an MK-801-induced psychosis model in mice. It is applicable for research related to schizophrenia.

Ancitabine is an antitumour drug that improves Hailey-Hailey disease-related phenotypes in yeast models. It is metabolised to cytarabine in vivo and inhibits DNA synthesis, primarily used for treating acute leukaemia.

Hepln-13 is a hepsin inhibitor that acts by hindering prostate cancer bone metastasis.

NCDM-32B, a novel potent and selective KDM4 inhibitor, impairs viability and transforms phenotypes of basal breast cancer.

SRI-29132 is potent; highly permeant of the blood-brain barrier; and selective for LRRK2 kinase activity, therefore effective in attenuating pro-inflammatory responses in macrophages and in rescuing neurite retraction phenotypes in neurons.

Quorum sensing is a regulatory process used by bacteria for controlling gene expression in response to increasing cell density.[1] This regulatory process manifests itself with a variety of phenotypes including biofilm formation and virulence factor production.[2] Coordinated gene expression is achieved by the production, release, and detection of small diffusible signal molecules called autoinducers. The N-acylated homoserine lactones (AHLs) comprise one such class of autoinducers, each of which generally consists of a fatty acid coupled with homoserine lactone (HSL). AHLs vary in acyl group length (C4-C18), in the substitution of C3 (hydrogen, hydroxyl, or oxo group) and in the presence or absence of one or more carbon-carbon double bonds in the fatty acid chain. These differences confer signal specificity through the affinity of transcriptional regulators of the LuxR family.[3] C16:1-Δ9-(L)-HSL is a long-chain AHL that functions as a quorum sensing signaling molecule in strains of S. meliloti.[4],[5],[6],[7] Regulating bacterial quorum sensing signaling can be used to inhibit pathogenesis and thus, represents a new approach to antimicrobial therapy in the treatment of infectious diseases.[8] Reference：[1].

C18-HSL is one of four lipophilic, long acyl side-chain-bearing N-acylated homoserine lactones (AHLs) produced by the LuxI AHL synthase homolog SinI, involved in quorum sensing signaling in S. meliloti, a nitrogen-fixing bacterial symbiont of the legume [M. sativa]. C18-HSL and other hydrophobic AHLs tend to localize in relatively lipophilic cellular environments and cannot diffuse freely through the cell membrane. These long-chain N-acylhomoserine lactones may be exported from cells by efflux pumps or transported between communicating cells via extracellular outer membrane vesicles.

N-acylated homoserine lactones (AHLs) are a class of autoinducers used in bacterial quorum sensing to control gene expression in response to cell density. These molecules, comprising a fatty acid coupled with homoserine lactone (HSL), vary in acyl group length (C4-C18), C3 substitution (hydrogen, hydroxyl, or oxo group), and the presence of carbon-carbon double bonds, determining signal specificity through LuxR family transcriptional regulators.
