cas: 1337878-62-2 ATI-2341 ATI2341 CBNumber: CB93159454 Chemical Name: ATI-2341 Molecular Formula: C104H178N26O25S2 Formula Weight: 2256.85 CAS No.: 1337878-62-2 ATI-2341 is a potent and functionally selective allosteric agonist of C-X-C chemokine receptor type 4 (CXCR4), which functions as a biased ligand, favoring Gαi activation over Gα13. ATI-2341 activates the inhibitory heterotrimeric G protein (Gi) to promote inhibition of cAMP production and induce calcium mobilization. ATI-2341 is a potent and efficacious mobilizer of bone marrow polymorphonuclear neutrophils (PMNs) and hematopoietic stem and progenitor cells (HSPCs). ATI-2341 induces CXCR4- and G protein-dependent signaling, receptor internalization, and chemotaxis in CXCR4-expressing cells. It is the most potent agonist with an EC50 value of 194 ± 16 nM and an intrinsic activity of 81 ± 4%. ATI-2341 is a potent and efficacious mobilizer of bone marrow PMNs(polymorphonuclear neutrophils) and HSPCs(hematopoietic stem and progenitor cells) and could represent a previously undescribed therapeutic approach for the recruitment of HSPCs before ABMT(autologous bone marrow transplantation). ATI-2341 is able to induce chemotaxis of CCRF-CEM cells, inducing the typical bell-shaped curve observed with chemotactic agents ATI-2341 is a potent and selective allosteric agonist of chemokine CXC-type receptor 4 (CXCR4) that functions as a biased ligand, favoring Gαi activation over Gα13. ATI-2341 does not promote β-arrestin recruitment. ATI-2341 promotes the mobilization of PMNs and HSPCs in the peripheral circulation of both mice and monkeys.

cas: 3258-02-4 N(4)-hydroxycytidine EIDD-1931 N4-hydroxycytidine and its prodrug EIDD-2801 is being studied for its activity against a number of viral infections including influenza, MERS-CoV, and SARS-CoV-2 N4-Hydroxyctidine, or EIDD-1931, is a ribonucleoside analog which induces mutations in RNA virions.1,2 N4-hydroxycytidine was first described in the literature in 1980 as a potent mutagen of bacteria and phage.5 It has shown antiviral activity against Venezuelan equine encephalitis virus,1 and the human coronavirus HCoV-NL63 in vitro.4 N4-hydroxycytodine has been shown to inhibit SARS-CoV-2 as well as other human and bat coronaviruses in mice and human airway epithelial cells.3 It is orally bioavailable in mice and distributes into tissue before becoming the active 5’-triphosphate form, which is incorporated into the genome of new virions, resulting in the accumulation of inactivating mutations.2 In non-human primates, N4-hydroxycytidine was poorly orally bioavailable.6 A remdesivir resistant mutant mouse hepatitis virus has also been shown to have increased sensitivity to N4-hydroxycytidine.3 The prodrug of N4-hydroxycytidine, EIDD-2801, is also being investigated for its broad spectrum activity against the coronavirus family of viruses.3 N4-Hydroxycytidine (3258-02-4) was originally identified as a mutagen effecting AT to GC base-pair transitions.1 It has also been found to have antiviral properties against a broad range of viruses including hepatitis C2, norovirus3, Ebola virus4, Chikungunya virus5, influenza and respiratory syncytial viruses6, and importantly, coronaviruses.7,8 N4-hydroxycytidine is the active molecule in the antiviral pro-drug clinical candidate EIDD-2801

cas: 19608-29-8 CB-03-01 BREEZULA Hair Loss Cure What is CB-03-01? CB-03-01 (cortexolone 17α-propionate, CB0301) 1% cream is a topical androgen receptor inhibitor which has mainly been developed for the treatment of acne vulgaris (1). It is also presently being investigated in a large phase II clinical trial for the topical treatment of male-pattern baldness. CB-03-01 has been found to inhibit the androgen receptor regulated pathway (1). Also known as clascoterone, CB-03-01 is being developed by Cassiopea (a spin-off company from Cosmo Pharmaceuticals) and was initially commercialised as Breezula. Data from 2020 reveal that clascoterone is also being marketed as Winlevi for the management of acne vulgaris. CB-03-01 is thought to compete with DHT for its binding to androgen receptors in both the sebaceous gland and dermal papilla cells within hair follicles. The difference between Winlevi and Breezula is that Breezula is a solution that contains a higher concentration of the drug for the treatment of male-pattern baldness(2). In 2019, Cassiopea announced positive phase II 12-month results for their flagship product Breezula in the management of androgenetic alopecia. The phase II clinical trial recruited in excess of 400 participants in Germany and sought to evaluate the efficacy and safety of 4 different dosing regimens of CB-03-01 compared to vehicle agents in male subjects between the ages of 18 and 55 with mild to moderate male-pattern baldness. All participants were randomised to either apply CB-03-01 or a vehicle agent to balding areas of the scalp daily for 12 months. 5 treatment groups were analysed – 2.5% solution twice-daily, 5.0% solution twice-daily, 7.5% solution twice-daily, 7.5% solution once-daily, and vehicle solution twice-daily. Researchers used target area hair count (TAHC) and hair growth assessment (HGA) score as the primary end-points of interest. For TAHC, statistically significant changes versus the vehicle agent were observed in all of the active treatment groups, with the most significant improvements observed in the 7.5% twice-daily
