However, designing supramolecular gelators is challenging. Herein, a crystal engineering-inspired, structure–property correlation-based strategy was employed to synthesize a series of carbamoyl azide–drug conjugates as potential supramolecular gelators. Five non-steroidal anti-inflammatory drugs (NSAIDs), ibuprofen (<strong>Ibu</strong>), naproxen (<strong>Nap</strong>), ketoprofen (<strong>Keto</strong>), flurbiprofen (<strong>Flur</strong>) and diclofenac (<strong>Diclo</strong>), were used as starting materials to synthesize carbamoyl azides. The synthesized carbamoyl azides were isolated in good yields and characterized by single-crystal X-ray diffraction (SXRD) alongside FT-IR spectroscopy, <small>¹</small>H and <small>¹³</small>C NMR and mass spectrometry. Single-crystal structural analysis revealed that the self-assembly of these molecules, leading to gelation-conducive 1D hydrogen-bonded networks in all the carbamoyl azides, is driven by N–H⋯O interactions involving the amide functionality, as anticipated. Two of the carbamoyl azide–drug conjugates, namely <strong>Nap-Az</strong> and <strong>Diclo-Az</strong>, were gelators, producing supramolecular gels in aqueous solvents (DMSO/water) at room temperature. The anti-inflammatory activity of <strong>Diclo-Az</strong> against lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages was confirmed by the PGE<small>₂</small> assay. Studies conducted using the melanoma cell line (B16-F10) revealed that <strong>Diclo-Az</strong> exhibits appreciable anti-melanoma properties, displaying apoptosis induced cell death, whereas it was noncytotoxic toward the normal skin fibroblast cell line E. Derm. Interestingly, growth-delay experiments carried out on 3D multicellular spheroids derived from B16-F10 cells proved the effectiveness of <strong>Diclo-Az</strong> to retard and completely destroy the spheroids, thereby simulating its anti-tumour properties. The aqueous gel of <strong>Diclo-Az</strong> showed an excellent rheo-reversible property over a few cycles, suggesting its application <em>via</em> the topical route. Moreover, a small patch of <strong>Diclo-Az</strong> gel adherable to a commercially available medical bandage provided proof-of-concept for its utility as a vehicle-free drug delivery system.</p>","PeriodicalId":70,"journal":{"name":"CrystEngComm","volume":" 20","pages":" 3210-3224"},"PeriodicalIF":2.6,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148011680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They combine the functional richness typical of biomolecules with the synthetic accessibility and crystallographic tractability characteristic of small-molecule systems. Their favourable physicochemical properties and exceptional structural diversity make them difficult to replicate with other classes of molecular building blocks, while enabling systematic exploration of sequence–structure relationships in crystalline materials. At the same time, short-peptide crystals are often regarded as conformationally labile, a feature that has traditionally been viewed as an obstacle to predictive peptide crystal engineering. Recent studies, however, suggest that conformational flexibility in short peptides can shift from being treated as a crystallographic complication to being explored as a potentially controllable structural variable. A key challenge is distinguishing genuine crystal-state conformational control from apparent structural changes arising from crystallisation pathways, phase conversion or recrystallisation. In this Highlight we propose a practical framework for identifying when conformational lability translates into experimentally demonstrable conformational control in peptide crystals. We discuss representative model systems, outline experimental strategies required to distinguish crystal-state conformational selection from pathway-dependent effects, and highlight emerging cases in which controlled peptide conformation influences structural organisation and functional behaviour in molecular materials.</p>","PeriodicalId":70,"journal":{"name":"CrystEngComm","volume":" 21","pages":" 3284-3292"},"PeriodicalIF":2.6,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2026/ce/d6ce00117c?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148141600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a systematic study on the ion doping effects on the photorefractive properties of LN and LT crystals was performed. Pr:Fe:LiNbO<small>₃</small> and Zn:LiTaO<small>₃</small> crystals with different doping concentrations were successfully grown by the conventional Czochralski method.

In this study, we report and discuss the elusive nature of the second form (form II) of the favipiravir–theophylline cocrystal. This form was obtained only once and never appeared again despite extensive crystallisation efforts. In contrast, the previously identified form I has consistently emerged under a wide range of crystallisation experiments. This observation prompted us to investigate the underlying structural, thermal and energetic characteristics of the system. Single-crystal X-ray diffraction revealed distinct structural differences between the two forms; form I exhibits a homosynthon, whereas form II contains a heterosynthon between favipiravir and theophylline. Variations in synthons impart distinct crystal packing arrangements to each form. Differential scanning calorimetry (DSC) and powder X-ray diffraction (PXRD) were employed to assess thermal behaviour and phase transitions. The results indicate that form I is the thermodynamically stable polymorph, while form II represents the kinetic polymorph. Furthermore, lattice energy calculations and Hirshfeld surface analysis confirm the greater stability of form I. Despite the favourable synthon energy associated with the heterosynthon in form II, form I is favoured due to its overall higher lattice stabilisation energy. Additionally, packing efficiency and crystal density calculations showed that form I has a higher packing index, which contributes to its enhanced stability over form II.
